Some additional useful information to add to the technical details Scott
shared in his email. The reason you are noticing these changes now is
because we rolled out Parsoid-based-read-view rendering to svwiki
recently [1]. But, enwiki is still not using Parsoid (but will also
start using Parsoid in the coming months), so the difference you are
seeing between svwiki and enwiki is because of this.
In his email, Scott pointed to the phab task / gerrit patch [2] that
introduced the extra span in the DOM structure. Separately, he also
pointed to a change [3] that might roll out soon that might make Parsoid
and the old parser emit the span wrapper identically. But, as he notes,
the API and the read view code paths could be reconciled so that the
outputs could match better. Till we make that fix, you will notice the
difference between the API and the DOM structure.
Hopefully this helps clarify why you are noticing this now.

Hi!
We are working on the Wikispeech extension and have run into an issue
on Swedish Wikipedia (svwp) where the page title DOM seems different
both from the *displayTitle*returned by the API and from what we see
on other wikis.
For example, if we query:
*https://sv.wikipedia.org/w/api.php?action=parse&format=json&page=Apa&prop=displaytitle&formatversion=2
<https://sv.wikipedia.org/w/api.php?action=parse&format=json&page=Apa&prop=displaytitle&formatversion=2>*
we get:
*{"title":"Apa","pageid":3877894,"displaytitle":"<span
class=\"mw-page-title-main\">Apa</span>"}}*
However, in the actual DOM on svwp, the title appears wrapped
differently, for example:
*<span lang="sv" dir="ltr"><span
class="mw-page-title-main">Apa</span></span> + editsection span*
*
*
So it adds an extra *<span>*..
What confuses us is that this seems to behave differently from other
wikis we have tested, such as enwp, where the title DOM appears as the
*displayTitle*structure.
Is there something specific about svwp that causes the page title DOM
to be wrapped differently from other wikis, or has there been any
updates regarding the structure?
Kind regards,
