Previously, the inline help shown next to host tag dropdowns on the host configuration page could display the wrong text — often a help text configured on a different, unrelated tag group. In the worst case, the help text from a single custom tag group appeared on every host tag dropdown, including built-in tag groups.

The stored tag configuration was never affected.
