@raquelmsmith can you help with the merging of this PR, if you like the changes?

[Justicea83]

@neilkakkar not sure if you can help me assign a reviewer.

I also want to ask, it there a process for asking for review in this repo.
Check the contributing doc, didn't find such info

[raquelmsmith]

this should get thorough front-end review before it is merged as we have lots of buttons all over the place.

[Justicea83]

Alright sure, maybe we need a secondary testing organization like Applause, to speed this up.

[Justicea83]

Meanwhile I will take a look at something else.

Thanks @raquelmsmith

we have lots of visual regression tests so I'm not that concerned, just want to take a manual poke around to be extra sure :) will do that on monday!

Thank you for looking into this!

This is not the fix though. We need position: relative on .LemonButton e.g. for position of actions in LemonButtonWithSideAction. This also doesn't seem to actually fix the issue.

The real fix is removing the .Plugins__Popconfirm class, which has a problematic z-index that we no longer need.

Hmm, I believe something went wrong when rebasing/merging, because there are many commits considered part of the diff, which already are in master

This PR is messed up, I'll close it out and open another one
