Loop in Semantic model detected in UI, not when loading .items file

[crazyelectron-io]

OpenHAB 4.1.0.

When accidentally creating a loop in the semantic model for a Group Item (made it member of itself while mass-editing) with an .items file, no error/warning is logged. Only when selecting the Locations-tab in MainUI an error is displayed:

A a loop has been detected in the semantic model: alarmSystem is both descendant and parent of alarmSystem. Please correct and refresh.

(also notice the grammar error in the message "A a loop..." :grin:)

I would have suspected the check to be done at file load time (and logged accordingly).

UPDATE: It looks like when removing the offending group membership from the Items file and trigger a reload by saving it, an error entry appears in openhab.log:

ERROR] [s.internal.SemanticsMetadataProvider] - Recursive group membership found: alarmSystem is both, a direct or indirect parent and a child of alarmSystem.
