I was able to reproduce the failure by running: 
run-webkit-tests svg/animations/animate-end-attribute-numeric-precision.html --iterations 1000 -f -1

I saw intermittent failure all the way back to r233000. This test seems to have been flakey for a while.

Marked test as flakey in https://trac.webkit.org/changeset/235468/webkit

I am trying to remove this test in favor of WPT here: https://github.com/WebKit/WebKit/pull/22281

WPT variant passes and don't have any platform specific expectation.

Once landed, I will mark this as 'RESOLVED CONFIGURATION CHANGED'. Refer to 'See Also'.
