Prabhjyot Singh updated AMBARI-26561:
-------------------------------------
Description:
After upgrading *jQuery to 3.7.1* and updating {{{}jquery-migrate.js{}}}, the
Ambari UI fails to render the *Hosts* page.
The failure occurs because {*}{{$.browser}} was removed from jQuery starting
from version 1.9{*}, and the legacy plugin code in {{jquery.typeahead.js}}
still depends on browser detection logic like {{{}$.browser.chrome{}}}.
This results in a runtime error and breaks initialization of the Typeahead
component.
