@LGoto, is this still an issue? Could we get a screenshot showing the problem?

Seems to work on desktop, and in the mobile web browser on Android. Might still be an issue in the Android app, but this ticket is over a year old. Is it still reproducible?

(I recall there's some way to get the android app to point to testwiki, but I can't remember how...)

Over to @ABorbaWMF for testing

Hello, I'm a little unsure about the expected result. It appears to be working for me. Here is what I see:
Android App

Mobile Web

@LGoto and/or @cscott does this appear correct?

The payload from the reference:

{"selectedIndex":0,"referencesGroup":[{"id":"cite_ref-1","rect":{"top":169.78125,"right":28.45833396911621,"bottom":183.1145839691162,"left":16,"width":12.458333969116211,"height":13.333333969116211,"x":16,"y":169.78125},"text":"[1]","html":"<a rel=\"mw:ExtLink\" href=\"http://example.org\" class=\"external autonumber\"></a>","href":"./Ref_with_external_link_bug_test#cite_note-1"}],"href":"./Ref_with_external_link_bug_test#cite_note-1"}

We use the content in the html, which the <a> tag does not have a text in <a></a> and that causes the empty content in the reference bottom sheet.

Moving this on, I think it is fixed on 2.7.50422-r-2022-10-24
