The details

Resolves

Fixes comments being positioning incorrectly when loading from XML in RTL mode

Proposed Changes + Reasons

Makes it so that comments are positioned relative to the toolbox when loading in RTL mode, to match blocks.

To get this to work the same as blocks I had to change how I was handling RTL in the comment view. We can't apply the scale at the top level because that messes up the transform (we still want +x to go right and +y to go down in RTL mode to match blocks). So I need to apply it to the sub elements of the icon. And to get rotating the foldout icon to work, that meant I needed an element to encompass the elements of the top bar.
