The failure is caused by different fonts being used to renderer the time stamp. The current test expectations appear to rely on some type of renderer-related state being carried over from previous tests.

I discovered this bug using this CL: https://chromium-review.googlesource.com/c/chromium/src/+/1259722
Which always resets the renderer between successive runs of layout tests.
