If you'll could help with removing the two Bluetooth entries from #5317 that'd be great.

The Chrome stability check failed:

No output has been received in the last 10m0s, this potentially indicates a stalled build or something wrong with the build itself.
Check the details on how to adjust your build configuration on: https://docs.travis-ci.com/user/common-build-problems/#Build-times-out-because-no-output-was-received
The build has been terminated

This cannot be because of the change itself. @bobholt, can you investigate?

I'll merge this manually.
