Description

Found in SDK 19318

Steps to reproduce:
1. Compile and run the attached MXML application "TH12621.mxml". This application contains 3 top-level components

• a rect with a gradient fill
• a HorizontalLayout group containing a yellow rect with 50% alpha
• a copy of the group, with a Top constraint instead of a height
  These 3 items should be exactly visually aligned with each other, because the 1st and 3rd item have the same left, right, top, and bottom constraints, and the middle item (the yellow group) has the same left, bottom, and right constraints and an appropriate height.

Actual Results: the topmost item - the group with a top constraint - draws as a thin line.

Expected Results: the topmost item draws as a red rectangle, exactly aligned with the transparent yellow rectangle and the gradient-filled rectangle.

Workaround (if any):
