platform/ios/ios/fast/coordinates/range-client-rects.html seems to be broken on iOS since r266028.

Strange; I saw this with an earlier version of my patch, but I thought I had fixed it. Note that we don’t see the failure in EWS.

[Darin Adler]

Any clue why we didn’t see the failure in EWS?

Yeah, I tried to explain in https://bugs.webkit.org/show_bug.cgi?id=215677#c11
Basically ios-wk2 EWS was broken for some time late last week, showing green bubbles while the tests weren't even run (due to Bug 215742). I am going to fix EWS, so that in such infrastructure failures it doesn't show green bubbles, and instead keep re-trying.

[Darin Adler]

I”ll work on fixing this.

As long as no one merges this to the branch, we have some time to get it fixed.

This test is peculiar. The whole thing runs just fine cross-platform. It's just that the meta tag for zooming has no effect on platforms like Mac. But the bug/regression reproduces everywhere and has nothing to do with the zooming.

I think we should consider moving it out of the platform/ios/ios directory into a cross-platform directory.

[Alexey Proskuryakov]

I tried to follow the history to see why it was iOS-only, but had to stop at r167371 (moving from Internal).

[Darin Adler]

I think the intent was to check the meta tag behavior and there just happens to be no similar bug elsewhere.
