Cannot save updates to user-defined variables in the Variables document

[a-s-russo]

When I make changes to user-defined variables in the Variables document of my workspace, certain changes such as inserting new ones or removing existing ones, will not be saved. In one instance, when I click on 'Save Workspace', the underlying XML file is not updated, and in another instance, I cannot even select 'Save Workspace' as it is greyed-out. The only solution to save my changes appears to be selecting 'Save Workspace As...' instead, which is highly undesirable.

Below is an example video of not being able to insert a user-defined variable:

cannot_insert_variable.mp4

Below is an example video of not being able to remove a user-defined variable:

cannot_remove_variable.mp4

FYI @Immurb I added some videos to this issue to explain the problem further.

Yeah this is definitely a bug. The internal classes change their state successfully, but don't communicate it to the UI elements.
