LayoutTest mathml/wbr-in-mroot-crash.html timing out on mac-wk2 release

<https://build.webkit.org/results/Apple%20El%20Capitan%20Release%20WK2%20(Tests)/r201288%20(6249)/results.html>
<http://webkit-test-results.webkit.org/dashboards/flakiness_dashboard.html#showAllRuns=true&tests=mathml%2Fwbr-in-mroot-crash.html>

stderr output:
TestController::resetStateToConsistentValues failed
#PROCESS UNRESPONSIVE - com.apple.WebKit.WebContent.Development (pid 1590)
Comment 1 Alexey Proskuryakov 2016-05-23 13:12:41 PDT 
Previously, we didn't report a failure to reset the state to consistent values, and just silently relaunched the process.

Quite surprising that this happens on this particular test.
Comment 2 Ryan Haddad 2016-05-23 17:22:09 PDT 
I have not been able to report this timeout locally. Marked test as a timeout on mac release in r201306
Comment 3 Ryan Haddad 2016-05-24 12:55:59 PDT 
Marked as flaky on ios-simulator-wk2 release in <https://trac.webkit.org/r201344>

I am still working to reproduce this timeout locally.
Comment 4 Alexey Proskuryakov 2016-06-01 15:35:52 PDT 
I can hit this on a debug build when running tests like this:

run-webkit-tests mathml/very-large-stretchy-operators.html mathml/wbr-in-mroot-crash.html --iter 100 --debug-rwt-logging
Comment 5 Alexey Proskuryakov 2016-06-01 15:42:34 PDT 
Unsurprisingly, WebContent process is busy painting the previous test.
