New z-index is breaking other functionalities

The problem is because of the z-index change.

I don't know what happened in #4, I was just trying to reply:

We noticed this too, and for us Gutenberg is more important than Devel, so I've reverted the #3335841 patch:

I opened an issue over at the Gutenberg module 🐛 Gutenberg fullscreen mode + Admin Toolbar >= 3.3.1 + Gin hides the submit buttons Closed: works as designed .

As described in the Gutenberg issue, there is no straightforward way for us in Gutenberg to keep up with the high z-indexes, because we have a lot of tooltips, modals and so on, that would be affected by the change/need to be changed accordingly.

It seems to be more straightforward to revert the changes with a patch, until we have a better solution. Do not now, why this CSS specification in the current 3.x is duplicated at two places.

The patch looks good.

I'm not sure if it should be RTBC, because it just reverts what has been committed recently, but it should be reconsidered for sure, since as reported in 🐛 Admin toolbar menu z-index sucks with devel module Needs review the aggressive z-index has a negative impact on a couple of modal/dialog related functionality in core and contributed modules. The regressions seem to be much more drastic than the comparable small glitch with the devel debugging output.

Yes, I agree. I would prefer it to be reverted over applying the patch as a "new issue fix" since it is a regression introduced by the given change. If you find a more suitable status for this issue, please go ahead and change it.

This is a problem with CKEditor too. Toolbar overlays CKEditor menu when CKEditor is maximised → had previously fixed this with z-index 9990.

I;m closing this issue and reverting the other one
