Did some r/b: https://treeherder.mozilla.org/#/jobs?repo=autoland&searchStr=android%2C7.0%2Cx86-64%2Cdebug%2Cweb%2Cplatform%2Ctests%2Ctest-android-em-7.0-x86_64%2Fdebug-web-platform-tests-e10s-8%2Cw%28wpt8%29&fromchange=4646d2e361f61fd2feae6c33e8545cad55f1c28f&tochange=5c09de23289c0410840df6264d648ca6fd7f44c0&selectedJob=248354255

Asked the dev to take a look here https://bugzilla.mozilla.org/show_bug.cgi?id=965637#c148

If it helps, these jobs can be run on try with a recent-ish pull of mozilla-central. mach try fuzzy -q "android debug web-platform" should select all of the chunks, or you can specifically pick chunk 8 from that platform.
