Comment:

 At first, I got confused because it says that the theme has an option for
 enabling a sticky menu.
 I tried to look for an actual option in the Customizer, but did not find
 one.
 So I assume the sticky menu is the default behavior when a menu is
 assigned to the "Top Menu" menu location.

 I am able to reproduce the issue on WordPress trunk on Windows 11 using
 Chrome and Firefox.

 Patch
 https://core.trac.wordpress.org/attachment/ticket/42598/%2342598.patch
 can not be applied, it seems it is missing the path to the file.
 When I add the changes manually to the file, it solves the problem. I get
 somewhat different results in Chrome and Firefox, it does not scroll to
 the exact same position.
 I do not see a visible "second" layout shift, like in the videos shared in
 the ticket.
