Split from T97961:

1. Search anything on https://translatewiki.net/wiki/Special:SearchTranslations
2. Click on the ellipsis ... and on a group, for instance "MediaWiki"

I. Observed: the usual group selector appears for few instants with a list of subgroups, then the page is reloaded. For me, it's also in a wrong position (partly outside the screen.
II. Expected: don't load the group selector. Since T97961, I'm expected to click on an item of the list in the reloaded page.
