==================== Summary ====================

Name: HelpSystem-Core-ct.161
Author: ct
Time: 2 August 2026, 10:56:38.2225 pm
UUID: aacb7115-df22-41eb-8027-5156ac95e130
Ancestors: HelpSystem-Core-ct.159

Fixes a MNU when trying to drag a help topic away from a parent that doesn't support removal (such as the 'What is New?' topic in the welcome workspaces).

I don't insist on merging this into the release, but we could do...
