Difference
<text id="revision"> legend every test carries: it renders in a fallback font this
library cannot match, so it is excluded from the comparison entirely rather than failing every test.
If the useragent doesn't support CSS, this test does not apply. The test has passed if when clicking each of the rects the clicked rect turns blue - note that only the clicked rect must turn blue, if any other rect turns blue too then the test has failed. The reference image shows the final state, what the result should be after all rects have been clicked.
