Oh I see, this is chrome MV2... I could fix this, but MV2 is basically dead on chrome, are you working on a legacy enterprise extension? I think that's the only place MV2 still works on chrome, at least until google kills it in June 2025.

Oh weird!

I thought I had caught this originally in Firefox, but I can't repro there:

I guess its a non-issue. I only use MV2 in Firefox

OK, yup, this issue used to happen in firefox, but that was fixed a few weeks ago: #1199
