Can't set flags

[Kovoschiz]

I'm submitting a bug report

Brief Description

Set flags (I don't really care about thumbs up/down)

What is the current behaviour, (attach relevant screenshots) ?

Flags menu doesn't show. No console messages.

What is the expected behaviour ?

At least the flags menu should show up (then I can try to select the flags to see if that works)

When does this occur ?

Always. I checked that https://osmcha.org/api/v1/changesets/*/set-good/ etc requests are successful.

How do we replicate the issue ?

1. Rate good/bad
2. Click "Tags"

Please tell us about your environment:

• Firefox 122.0
  • Enhanced Tracking Protection off (I forgot how to unblock this one Google Analytics thing on basic protection, but it shouldn't matter?)
  • DuckDuckGo Privacy Essentials disabled
  • NoScript allowed all
• Linux Mint 20.2

(Per // this fails for some browsers. :( comment, and naming, it seems unrelated)
At least 32 WebGL warning: texImage: Alpha-premult and y-flip are deprecated for non-DOM-Element uploads. (not reported afterwards)
CSS:

• Many Error in parsing value for ‘user-select’. Declaration dropped. <changeset>:1:1
• A few of this

Ruleset ignored due to bad selector. assembly.min.css:1:102125
Ruleset ignored due to bad selector. assembly.min.css:1:102361
Ruleset ignored due to bad selector. assembly.min.css:1:102434
Ruleset ignored due to bad selector. assembly.min.css:1:102579

• Unknown pseudo-class or pseudo-element ‘-ms-fill-upper’. Ruleset ignored due to bad selector. etc
• Expected media feature name but found ‘-ms-high-contrast’.

If you need a HAR file etc, you can give me a changeset to try. Don't want to try rating random changesets arbitrarily.
