The following layout test is flaky (timing out) on macOS-Mojave Debug WK2. webgl/2.0.0/conformance/state/gl-object-get-calls.html Flakiness Dashboard: https://webkit-test-results.webkit.org/dashboards/flakiness_dashboard.html#showAllRuns=true&tests=webgl%2F2.0.0%2Fconformance%2Fstate%2Fgl-object-get-calls.html
This is a slow test that usually takes more than 20 seconds, but it times out a lot on Apple Mojave Debug WK2.
I cannot reproduce this timeout locally with 500 iterations. Should we mark it slow on Mojave Debug WK2?
Skipped the test for Mojave Debug WK2 in https://trac.webkit.org/changeset/245059/webkit
This is a slow test, so I think this is the correct resolution.
