The regression range is fairly large since the test last passed on 247094@main and started failing on 247262@main without any builds to test on between the two commits.

I'm unable to state that 247262@main is the root cause because of this (most likely isn't).

This issue can be bisected to 247262@main using command: 

run-webkit-tests --release --ios-simulator --iterations=2   svg/transforms/transformed-text-fill-gradient.html

Reviewed commits have been landed. Closing PR #3616 and removing active labels.

Worth noting:

This test has been failing for a long time on macOS. I'm not sure if this should be passing on all iOS queues?

[Alexey Proskuryakov]

This test was actually failing on arm64 iOS since it was imported.

Looks like dithering noise in the gradient.
