Following has been fixed and removed, but rest still applies:

• Infinite Style Dummy Editors

1) At the Page-level, adjust any of the current Padding values.
Observe how the language text does not change position, despite the Style values being overwritten.

2) Click on the Padding Property's '3-Dot' menu, and click on the 'Edit Resource' arrow to go edit the Style directly.
This will open the Style in an isolated Style Dummy Editor view.

3) Within the Style, adjust the Padding values.
Observe how the language text still does not change position.
(I assume this is due to a breakage where the Binding for 'Padding' was destroyed coming to Studio)

4) Within the Style: Click on the Padding Property's '3-Dot' menu, and click on the 'Edit Resource' arrow to go edit the Style directly.

5) Repeat Step 4) 10 times.

6) Exit the Style by clicking on the 'back' arrow in the Style's Dummy Editor's.
Observe how the same Style has been opened multiple times, requiring 10 clicks to exit this Style's dummy editor and returning back to the MainPage.

Expected Result: Opening a Style whilst its already open, does not 'stack' instances of it on top of itself, but instead, only keeps one instance of itself open at once.
