Test case

Open the attached test case.  It has a canvas on which two objects are drawn after setting the globalAlpha to 0.2. The first one is a solid red rectangle and the second is an SVG. The SVG simply draws a solid red rectangle also.

Result: The globalAlpha is applied to the rectangle but it is not applied to the SVG.
Expected: Drawing the SVG image should take into account the globalAlpha.
