I don't know why the counter is incremented twice for each concurrent
environment; the document is typeset once, in three passes. Dividing by two
solves the issue, if there's a deeper issue, I'm at a loss to explain it.

[NTG-context] Font switching, default features, and a request
Dear gang,
Consider the following example:
==
\setupdirections[bidi=global,method=one]
\startTEXpage[offset=1em,width=14in]
\definedfont[almfixed*arabic]
\switchtobodyfont[almfixed*arabic]
\switchtobodyfont[almfixed]
% \addff{arabic}
\startbuffer[]
\startlines
الثَّعْلَبُ الْأَسْمَرُ السَّرِيعُ يَقْفِزُ فَوْقَ الْكَلْبِ الْكَسُولِ!
The quick brown fox jumps over the lazy dog!
\stoplines
\stopbuffer
{\tfxx \type{\tfxx} \getbuffer}
{\tfx \type{\tfx} \getbuffer}
\type{\tf} \getbuffer
{\tfa \type{\tfa} \getbuffer}
{\tfb \type{\tfb} \getbuffer}
{\tfc \type{\tfc} \getbuffer}
{\tfd \type{\tfd} \getbuffer}
\stopTEXpage
==
There are three font switches to choose from:
==
\definedfont[almfixed*arabic]
\switchtobodyfont[almfixed*arabic]
\switchtobodyfont[almfixed]
==
Let's toggle one at a time:
1) \definedfont[almfixed*arabic]
a) gives us the correct bidi output, but only for the \tf size
b) is ignored for every other size switch.
a) and b) are expected behavior.
2) \switchtobodyfont[almfixed]
a) gives us Arabic-script bidi output,
b) exhibits no Arabic-script features
c) gives the same result for each size switch
This means that the fontfeature "arabic" -- already predefined in ConTeXt
(font-pre.mkiv) -- is not explicitly applied.
Curiously, invoking
\addff{arabic}
does not affect the output. Why is it that \addff{arabic} does not work here?
3) \switchtobodyfont[almfixed*arabic]
suppresses the font entirely and we're back to Latin Modern for all sizes.
Assuming that this is expected behavior, it appears to follow that fontfeatures
cannot be invoked for \switchtobodyfont and the like, only from within the
typescript read by \switchtobodyfont etc.
===
REQUEST:
Since ALMFixed is already distributed with ConTeXt, could Hans make the
fontfeature "arabic" default for this font? That is
\switchtobodyfont[almfixed]
should automatically
a) give us Arabic-script bidi output (already there),
b) exhibit Arabic-script features (missing)
c) gives the same result for each size switch (already there)
(Indeed, it would be useful to have *arabic-predefined typescripts/bodyfonts
for a few other commonly available/used Arabic fonts as well. Would be willing
to make a list at some point, test, etc.)
Thank you in advance for considering this request.
Best wishes

One can also try to instead use the accent mechanism instead of a stacker:
% engine=luatex
\definemathtopaccent[widebar] ["0305]
\startTEXpage[offset=3pt]
$\overbar{OA}$
$\widebar{OA}$
\stopTEXpage
The \widebar is defined (almost) like that in lmtx.

Not really. It's a a bug in the fonts (that will stay if only for
compaibility reasons). There is a catch in mkiv that compensates for it
but only when characters are not there. So, for these two I now force
the catch.
In lmtx we have a bit different approach: we just assuem they are wrong
in all fonts and fix them or replace them. We also have a more advanced
math engine so we can control placement better.
There are also 'font parameters' involved that can be bad (i guess that
designers can't really test math font parameters). In lmtx we have more
of them, beyond what opentype math provides.
All of this is handled in goodie files. That mechanism is present in
mkiv but no one ever bothered to spent time on it. That said: the last
two years Mikeal and I spent a *lot* of time on math and we don't really
look back at mkiv / mkii also because there is way more neat things now
(most probably go unnoticed) ... you can read about it in some documents
that come with context, articles in tugboat, and there are talks by
Mikael at tug meetings on YT.
The output with Luametatex is correct but Luatex creates a raised bar
(and different linebreaking).
\showglyphs
\startTEXpage[offset=1ex]
\ruledhbox{$\overline{OA} = \overbar {OA} = 4.2$}
\par
\ruledhbox{$\underline {OA} = \underbar {OA} = 4.2$}
\par
\ruledhbox{$\widetilde {OA} = \widebar {OA} = 4.2$}
\par
\ruledhbox{$\overbracket {OA} = \underbracket {OA} = 4.2$}
\stopTEXpage
I'll add a 'force fix in spite of extensible being present' in mkiv. In
lmtx we always fix also because we drop in nicer shapes (watch the round
tips in lm and fancy tips in antykwa) and concluded that fonts will
remain as they are.

As you suggested, I will give a try to LMTX but be aware most user still use
MKIV until most distros upgrade the texlive version of context to LMTX.
It's not that hard to install lmtx alongside. If distributions take from
texlive then likely you also end up with files that are not needed (base
package) and lack some fonts (esp math) by default. You'd also benefit
from the last couple of years advancements. Keep in mind that for a long
term tex (document) project a snapshot approach is healthy because you
never know what a distribution adds / replaces (esp fonts can be a mess
and you want to know what you use).
