fast/images/async-image-multiple-clients-repaint.html 

It has been flaky in a while. For wpe release:

The bot wpe-release completed 2910 runs on the interval [295530@main-305525@main]
Frecuency of results for test: fast/images/async-image-multiple-clients-repaint.html
  2790 times [95.9%]     ->  NOERROR
  104 times [3.6%]       ->  TEXT MISSING
  16 times [0.5%]        ->  TEXT

Of those 2910 runs it didn't match the expectation 120 times [4.1%]
Details of the type and frequency of unmatched expectations:
  104 times [3.6%]       ->  TEXT MISSING (Expected: PASS)
  16 times [0.5%]        ->  TEXT (Expected: PASS)

Flakiness factor: 7.7%
    - This test was flaky on 7.7% of the 2910 runs analyzed, either giving different
      results within a single run, or a different result than in the previous run.

Maybe some race condition from the usage of setTimeout?
