Bubble inherited from another master

[gorjious]

When there is a bubble in one master and no bubble or any back-up layers in another master, the second master inherits the bubble...is this a bug or feature? I can imagine it might be useful a feature if the masters would share the same kerning (not sure how you would distinguish which masters would inherit the bubbles or not), however, the issue is that it occurs only when there are no layers on the other masters...as soon as a new layer is added the bubble display is gone.
