Disappearing kb elements in Firefox Reader Mode

[Ezekiel Victor]

Preamble/environment

I don't know the extent of this bug—it's possible it may affect many more browsers, versions, and/or pages on this site. But here are my specifics which may be necessary to at least some extent (e.g. browser may matter):

• Browser: Firefox 91.0.2 (64-bit)
• OS: 13.4 (22F66)
• Document width/height: 1792×988

Steps to reproduce

1. Visit https://support.mozilla.org/en-US/kb/dns-over-https?as=u&utm_source=inproduct#w_configure-doh-protection-settings

   Details

   The URL hash zips you to the section of interest, Configure DoH protection settings.

2. Take note of these visible .menu items (not semantically great CSS class name but that's for another internal issue 😉) that appear as highlighted words in their respective sentences:
   

3. Enter Firefox Reader Mode:
   

4. Look for those .menu highlighted parts...

Expected

The .menu highlighted words should still be there.

Actual

They've vanished.

We should decide if we want to eliminate the .menu as a class that can be used in our wiki markup, file a bug with FF for readability mode aggression or move the issue out as a low impact/low priority. @akatsoulas @escattone I can confirm that the issue happens to items in documents classed with menu.

I believe @emilghittasv is/will open a FF bug. I'll leave this in backlog until we see the outcome.

This is now tracked in Firefox and it's not related to SuMo. Thanks @evictor for catching and filing this!
