Video LineHandleAdornment_Repo demonstrates that LineHandleAdornment Instance does not respect property Thickness (In Pixels).
The Thickness of the Line (or tube) varies against the size of the mouse, which is contrarily of constant pixel size.
Expected behavior
LineHandleAdornment should respect Pixel size in width from all view directions. LineHandleAdornment is meant to be sized in pixels, and not related to perspective or position in worldspace unlike all other Adornments.
