Add a test for backdrop filter underlapping a border

A recent bug [1] showed that in SkiaRenderer, it was possible for a
backdrop-filter element to blend pixels from a neighboring (but not
underlapping) render pass, due to some clipping issues. This test
checks for this situation.

The original bug was fixed in [2], but I verified that this test
breaks pre-[2] (see patchset 1 of this CL).
