Comment (by tusharaddweb):

 Tested this issue in Chrome and was able to reproduce the problem where
 the admin screen (Font Library/Connectors) does not mount properly.

 It appears to be caused by @wordpress/boot executing before its
 dependencies are fully loaded, leading to a race condition during
 initialization.

 After apply the patch, the issue is resolved and the screens load
 consistently. I did not notice any regressions in other admin pages during
 testing.
