It was still happening within this interval on May 15th - https://treeherder.mozilla.org/#/jobs?repo=mozilla-central&searchStr=windows%2C10%2Cx64%2Cccov%2Copt%2Cweb%2Cplatform%2Ctests%2Ctest-windows10-64-ccov%2Fopt-web-platform-tests-e10s-11%2Cw%28wpt11%29&tochange=a77ca5bd6b7c49099c672e103771ca2bf077cc40&fromchange=22a95484cc62214e768dd06711a542b589cb2116 but it looks like the failures weren't added to the orange factor as it misses the starring against this bug ( the failure line here is lower within the failure summary.)

The occurrences stopped appearing on this particular merge https://treeherder.mozilla.org/#/jobs?repo=mozilla-central&revision=f340bbb582d16c083344b1370bd4e4d4caf5fb17&searchStr=windows%2C10%2Cx64%2Cccov%2Copt%2Cweb%2Cplatform%2Ctests%2Ctest-windows10-64-ccov%2Fopt-web-platform-tests-e10s-11%2Cw%28wpt11%29 and based on the retriggers and backfills on autoland it can be confirmed that since then there were no more occurrences.
