For what it's worth, auto suggestions _do_ work on the same affected devices and sites from the search bar on Special:Search (OOUI; T100898).

I can also replicate this at will in Timeless, Vector, Example, and Poncho on Android Firefox, Firefox Preview, and Chrome, against both MW 1.33.1 and English Wikipedia. It also affects these mobile browsers when selecting "Desktop view". No desktop browsers appear to be affected (tested in Firefox 70+, Chrome, and Safari).

Apologies. I have no idea how I moved this, or how to move it back.

Thanks @SamanthaNguyen! That's enough to hack in a workaround for now. I just pasted mediawiki.action.view.dblClickEdit.js into MediaWiki:Refreshed.js and changed the selector.

Sorry, not sure how this got into MW general. I filed it from and for the Refreshed skin project.
