I am sorry for the mess, this gerrit is not very intuitive to me. The correct merge request is this one:
https://gerrit.wikimedia.org/r/c/mediawiki/extensions/UserMerge/+/985103
It should have every change required as discussed here:
https://gerrit.wikimedia.org/r/c/mediawiki/extensions/UserMerge/+/975018
What changes are needed, besides rebasing and resolving the merge conflicts (I'll do that shortly)

I encountered this problem when we have a widget (from Widgets extension) that has code of the form

<script>
if ( something && somethingElse ) {
  doStuff()
}
</script>

It replaced the &s by &s on MW 1.43.4 and 1.43.5

I saw you assigned to Wgevaert, which is my old account from before I worked at Wikibase Solutions BV. Is there any action from me required on this?

I have a proof-of-concept patch here:

For now we fixed by setting wgServer to not be protocol relative.

We did have a dependency problem on one of our wikis:

It seems this may be a duplicate/related to the other ticket in this workboard: https://phabricator.wikimedia.org/T383351

However, I think it would be better if the afterTidy callback was called only once. At least that was the intention by choosing that callback initially. A callback that is executed directly prior to printing out to HTML.

I tested the 1_39 patch I uploaded in gerrit, it seems to fix the issue.

What happens is as close as one can get to rendering only once. The code unsets already processed tags.

I believe that is a "s" in a funny font that looks like an "8".

See https://gerrit.wikimedia.org/r/c/mediawiki/extensions/UserMerge/+/975018

Did you apply the patch?

For me, doing the steps as described in https://www.mediawiki.org/wiki/Parsoid#Installation worked.

@Aklapper I would like to get this merged. All test results on the ticket seem to be gone, so I do not know what work should be done. What needs to be changed to the patch?

Dear Cicalese,

Could this be back-ported to the REL1_35 branch? There's been quite some refactoring between these branches, so I am not sure how easy this will be.

@Tgr Thank you for your reply!

For example, should [[Hello#World]] and [[Hello#World|Hello#World]] include the anchor in the link text?

Fixed by https://gerrit.wikimedia.org/r/c/mediawiki/extensions/DisplayTitle/+/856547 please merge
