Yeah, sounds like there's no easy solution, unless you realize that the
<dyn> dependency is spurious. You could try breaking it into multiple
smaller <dyn>s, maybe with some nested inside of others.

Hm! The original code is sketched below. I am not interested in
catching every event from <ctextbox> but the code expresses exactly
this, so you are right, Thanks!

PS by ctextinput I meant ctextbox
fun editable (t:string) (upd:string->transaction unit) =
<xml><active code={
st <- source t;
se <- source False; (*edit mode*)
...
return <xml>
<dyn signal={
t <- signal st;
e <- signal se;
return
<xml>
<ctextbox signal={t} onkeypress={... v <- get t; rpc(upd v); ... } />
</xml>
}/>
</xml>
}/>
</xml>

Is the control inside a <dyn> whose value is affected by a source that every
keypress updates? Focus is expected to go away every time a dynamic subtree
needs to be rebuilt.

Just found a strange issue regarding <ctextinput>. If used with
source={s} attribute set, the control looses input focus after every
keypress event. Removing source={s} brings back the correct behavior.
Is it a known issue?
As a workaround, I tried <ctextinput id={cid} source={s}
onkeypress={fn _ => giveFocus cid} /> with no improvement.
I'm using urweb-20170105 and firefox(nighty)-49.0
