It looks more like a bug, and I'm going to move subtype around so that more people know about it.

Hi @IN. We tested it on https://m.wikidata.org/w/index.php?title=Q2&action=history and the result is the screenshot here:

This looks good to me. Are you seeing something else? Or are you using a different system/browser/...?

Sorry, my content may be a little ambiguous. I mean is that the user contrib page edit summary is wrong:

Ah thank you. I can confirm this on https://m.wikidata.org/wiki/Special:Contributions/KrBot for example:

@Addshore do you know if this is on us to fix or WMF?

Although I don't know, but can you write a patch for it first?

After a very quick look around I' not really sure

All Wikibase does is hook into MediaWiki comment formatting ability
https://github.com/wikimedia/Wikibase/blob/16460156e9aecfd9ab577615c4042dd3f270ea04/repo/includes/RepoHooks.php#L660-L671
This is called from Linker::formatComment which should be called from all needed pages https://gerrit.wikimedia.org/g/mediawiki/core/+/ef5d312a08b9b31ce42cd205cdcb50db42c3d109/includes/Linker.php#1208
MobileFrontend seems to call that hook as needed https://gerrit.wikimedia.org/r/plugins/gitiles/mediawiki/extensions/MobileFrontend/+/e0869ee26adce00cc07b602bb6fb793a7f9f238c/includes/specials/MobileSpecialPageFeed.php#46

Probably needs someone to take a closer look

Ok cool. Thanks!

I also found similar errors in the testwikidata:

We discovered this additional issue while looking into this: T284978

@Jdlrobson Could you have a look at this please?

Perhaps showing the desktop version of this page makes sense for Wikidata?

desktop Version	MobileFrontend version

If so, we have the globals $wgUseDesktopSpecialWatchlistPage and $wgUseMFUseDesktopSpecialHistoryPage for disabling the watchlist and history page overrides but we don't seem to have one for the contributions page which would allow you to configure this off. Adding one would not be a large amount of work, and I'm happy to help support engineers on the Wikidata side if that's an option.

If that's not an option you'll want to talk to Olga about us carving some time out for this page. Development on this feature/page is pretty much frozen given the epic goal of T210168.

@Jdlrobson Thank you for your answer! We have just realized that this also concerns the mobile version of Wikimedia Commons:

Considering T210168 I guess you would still recommend we show the desktop version of this page on Wikidata, right? Would the same be true for Wikimedia Commons?

I've asked our product owner @ovasileva to wade in here about the best course of action.

Hi @Jdlrobson, thank you for reaching out to @ovasileva about this! Is there any news yet?

@Manuel, @Jdlrobson - Sorry for the delayed reply here. I think showing the desktop version for both wikidata and commons would be fine (@Lydia_Pintscher so long as that's okay with you) . That said, are we expecting this to be a wider issue? Do we know what is causing it?

No objections from my side :)

This will need a backport for wikidata once the feature flag is available (earliest Wednesday)
