Here are try pushes with pretty minimal requested jobs but a bunch of extra ones get scheduled.

In the first, I see you selected reftests for Aarch opt, and we scheduled build-win32-shippable/opt, build-win64-aarch64-shippable-no-eme/opt, build-win64-aarch64-shippable/opt.
It seems the tests depend on build-win64-aarch64-shippable/opt, which depends on build-win32-shippable/opt and build-win64-aarch64-shippable-no-eme/opt.
I have no idea why build-win64-aarch64-shippable/opt would depend on build-win32-shippable/opt and build-win64-aarch64-shippable-no-eme/opt :/

In the second I only see linting (always triggered) and Python tests (triggered as you modified some Python files), so nothing unexpected (though maybe we could avoid running Python tests on all platforms unless selected).

To enable widevine for windows aarch64 builds, we need a win32 plugin-container (since there is not a aarch64 widevine plugin). To that end, we combine extract those bits from the equivalent win32 build. The build-win64-aarch64-shippable/opt is a special artifact build that combines the build-win64-aarch64-shippable-no-eme/opt build with the win32 bits required.
(see Bug 1527463 for details).

Thanks! The only thing left to figure out is why shippable builds instead of opt ones were used for those tests.

I believe this is controlled by https://searchfox.org/mozilla-central/source/taskcluster/ci/test/test-platforms.yml#242
