Description Devin Rousso 2019-05-23 16:25:00 PDT 
<https://trac.webkit.org/r244353> caused fast/css/sticky/sticky-left-percentage.html to start failing (ImageOnlyFailing) <https://webkit.org/b/198195>.

```
Error: test and reference images have different sizes. Test image is 800x700, reference image is 800x600
ImageDiff crashed
```

I think this may be a problem with the timing of when the image snapshots are taken, as fast/css/sticky/sticky-left-percentage.html involves resizing the window before the test ends (adds an event listener for "load").
