This is the current situation which isn't exactly ideal... I am afraid that making this work, the way it did, without reversing some changes might not be possible

[SimonBrandner]

Yeah, I think I've run out of ideas... I think this is better than the current broken state, so I am making this ready for review

Hmm IRC mode seems very jumpy for me

to the point I can't even target the resizer

Though that's with & without this PR but not in current app release.

Hmm so even though this is experimental I don't think this solution is usable. It feels like the wrapping component encompassing both the name and disambiguation needs to remain and then the disambiguation just needs to be a span within that with alternative styling, that way it'll go back to like it was before being fit into the layout as a single element

Hmm, I haven't tested with timestamps hidden... That should probably be fixable, though I don't think we can get something better than what I've posted

[SimonBrandner]

I've pushed changes that should fix the timestamp issues. This is far from ideal, but I believe it should work reasonably well enough before we decide what to actually do next

This appears to at least fix the core regression, so let's merge this, and we can improved from there as needed. Thanks for working on this!
