TemplateStyles not applied in mobile talk page (overlay)
Closed, ResolvedPublic


Apparently, when viewing talk pages in the mobile version (or the app), potential TemplateStyles will not be applied to the "overlays container", which leads to rather strange outcomes in some cases. Obviously, there will always be templates on talk pages, so TemplateStyles must be applied also in the mobile view (and not just when continuing with "read as wiki page").

Random example: here the table is broken because of missing TemplateStyles

Developer notes

The talk overlay element with classes "content talk-section" needs to also add the class mw-parser-output

Hi @XanonymusX, can you please provide a full link to a web address where this issue can be seen? See - Thanks.

I have added an example (but it's obviously a general problem, since the overlays container simply does not contain the mw-parser-output class)

Hi jdlrobson,
Why did you reassign the task?

@Jdlrobson please update with some acceptance criteria or steps. I looked at the link in the description and the Talk:Dog page in Beta and they both look similar.

Wrote QA steps and ended up testing it myself :)

The link to production no longer works, so skipping QA in production as I don't have a good example.
