Critical: Backend Styles missing + JS Error

I was editing the header template part and reloaded the editor.
The styling vanished completely and a JS error appeared in the console:

react-dom.min.js?ver=18.2.0:10 TypeError: Cannot read properties of null (reading 'setAttribute')
    at Wc (index.js?ver=
    at index.js?ver=

    at yl (react-dom.min.js?ver=18.2.0:10:88450)

The frontend shows just fine, though.

Tested on another content page and pasted some hero from the lib. At first it appears good, but after reloading the styles are missing again.
Regenerating style sheets did not help.

The JS error is already present under “/wp-admin/site-editor.php”

Hello @oppi,

Thanks for the report.

I’m sorry to hear you’re having trouble here.

So that we can address this as soon as possible, would it be possible to have temporary access to this installation sent to if it is online?

Thanks in advance.

We were able to reproduce the issue on our end thanks to the access you provided.
The bug is related to Dark Mode attribute selectors.
