Bug: User Variable won't stay set if on General tab of Fragment Details.

[NormanRouxel]

Failure found on 8.5.1 and 8.5.2.

Scenario:
Go to Design / Library / Variables / Fragment.
Right-click Fragment and choose New Variable.
Set the new variable as follows:

Name:			HideFragmentOnWebSite
Description:		Whether to hide this fragment from display.
Prompt:			HideFragmentOnWebSite
Place Of Setting	Fragment	
Allow <Use Parent>...	Checked
Tab Name:		Layout
Type:			True/False
Upload:			Unchecked
Initial Value		Use Parent
Top Level Value		False

Now go to a Fragment in the Content Tree and try to set HideFragmentOnWebSite where you cannot get the value to stick.

If the Tab Name is changed to Layout, things work as expected.
