Open a translatable page for editing, do an innocent change, get useless error report.
E.g. I'm trying to save https://www.mediawiki.org/w/index.php?title=Manual:Developing_extensions&oldid=2696554 with this diff:

 <translate><!--T:316--> * Master: the master branch of the extension is compatible with as many old versions of core as possible. This results in a maintenance burden (backwards-compatibility hacks need to be kept around for a long time, and changes to the extension need to be tested with several versions of MediaWiki), but sites running old MediaWiki versions benefit from functionality recently added to the extension.</translate>
 <translate><!--T:317--> * Release branches: release branches of the extension are compatible with matching branches of core, e.g. sites using MediaWiki 1.27 need to use the REL1_27 branch of the extension. (For extensions hosted on [[gerrit]], these branches are automatically created when new versions of MediaWiki are released.) This results in cleaner code and faster development but users on old core versions do not benefit from bugfixes and new features unless they are backported manually.</translate>

(That is, break up the flow of translatable text with an untranslatable comment. None of the translation items are changed.)

I've tried a handful of different positions for the translate tag, to no avail.

(FWIW this is in new wikitext editor, not normal VE. I don't imagine it makes any difference.)
