After upgrading jQuery from 3.6.0 to3.6.3 pseudo selector :before does not work in selector list with Firefox. Everything works with Chrome.
This worked in 3.6.0
jQuery(".inline-dialog-content:before").css({'left': 40});
In 3.6.3 it gives following error:
Uncaught Error: Syntax error, unrecognized expression: unsupported pseudo: before
