Bug 172183 – [macOS Debug wk2] Layout test svg/animations/animations-paused-in-background-page-iframe.html is flaky

• Status: RESOLVED
• Resolution: FIXED
• Component: New Bugs

[Matt Lewis]

The test svg/animations/animations-paused-in-background-page-iframe.html is a flaky failure on macOS Debug wk2.

https://webkit-test-results.webkit.org/dashboards/flakiness_dashboard.html#showAllRuns=true&tests=svg%2Fanimations%2Fanimations-paused-in-background-page-iframe.html

https://build.webkit.org/results/Apple%20Sierra%20Debug%20WK2%20(Tests)/r216932%20(1029)/results.html
https://build.webkit.org/builders/Apple%20Sierra%20Debug%20WK2%20(Tests)/builds/1029

This does not appear to be a recent regression.

I was able to reproduce locally on Sierra Debug with:

run-webkit-tests svg/animations/animations-paused-in-background-page-iframe.html -f --iterations=219 -g
