Fixes #90791. There is a
handleSiteEditorBackButton
click handler that detects clicks on the Site Editor Dashboard link and does a custom handling on these clicks. The handler is buggy and can sometimes cause crashes (doesn't check ifelement
isnull
). And nowadays the handler no longer has any function, because we never iframe the Site Editor. See for example #76371 which was a part of the iframe deprecation effort a year ago.This PR simply removes the
handleSiteEditorBackButton
handler.
