Bug 1866874 [wpt PR 43377] - Address concerns about CSSStyleSheet-con…

…structable-concat.html, a=testonly

Automatic update from web-platform-tests
Address concerns about CSSStyleSheet-constructable-concat.html

See [1] for comments, but this CL adds reftest-wait to ensure
the test finishes before the image capture, and adds PASS lines
for all passed tests.

This makes no difference in Chromium, but ensures this test
works correctly in other browsers.
