Must be a side effect of <strong> being inside {{PLURAL}}. The PHP-based message implementation supports that, the JS-based apparently doesn't.

The same issue is also present in the task count in the suggested edit filters.

@Amire80 could you take a look at it?

The Messsages API docs say The doc-jqueryMsg template can be used to document such messages, to let translators know which wikitext restrictions apply. We should probably get in the habit of doing that.

Updated the Messages API docs to mention this edge case.

Thanks for the mention.

I've tried changing <strong> to ''', and I see an odd thing when I try to open Special:Homepage: it's initially loaded with correct formatting, and after a moment it changes to show the <strong> tags again. Not sure if it's a bug in the extension code or a caching issue.

... OK, it's a caching issue. I'm now trying again, and it shows me apostrophes instead of proper bold formatting.

I removed the formatting entirely.

Per https://www.mediawiki.org/wiki/Manual:Messages_API#Feature_support_in_JavaScript ''' is not supported either (and even if it would be, the nesting would probably still break). I think you should just omit the special-casing for when there's a single result (which should be very rare anyway).

Although I guess we could also just apply the formatting on the software side.

FTR, I cannot reproduce this now. Was this fixed on-wiki already?

I seem to recall translatewiki i18n changes being updated daily nowadays, so probably yes.

Re-checked on hewiki - aside from not displaying numbers in bold, the issue is not present anymore:

Numbers should be bolded	testwiki

The issue that @mewoph mentioned is not present anymore:

I can confirm this with my interface language set to Hebrew: https://he.wikipedia.org/w/index.php?title=%D7%9E%D7%99%D7%95%D7%97%D7%93:%D7%93%D7%A3_%D7%94%D7%91%D7%99%D7%AA&source=personaltoolslink&namespace=0&uselang=he; I cannot reproduce this with uselang=en. This is also reproducible locally.

I restored the local message in the Hebrew Wikipedia as a workaround, so now the bug is invisible there. You can still easily see the bug if you open the English Wikipedia with Hebrew user interface:

https://en.wikipedia.org/wiki/special:Homepage?uselang=he

Thank you, @Amire80! Should we keep this task open to follow up with a proper fix (if there is a proper fix) ? The message is displayed without markup now, but the numbers are not bolded, e.g. in enwiki:

I checked arwiki and fawiki - the message looks correct. And uselang=he will display the issue.

IMO not worth it, this task is already generating more bureaucratic overhead than it is worth. There is T249892: mw.message.parse() should not escape HTML returned from magic words (e.g. {{PLURAL}}) for tracking the underlying issue.

I'm trying to clean up Growth's sprint board. I'm moving this out of current sprint since it seems like work has stalled on this and it might be more work than it's worth. But feel free to reclaim and move back to the current sprint if I'm mistaken.
