The failure happens here:

https://dxr.mozilla.org/mozilla-central/rev/8d026c60151005ad942e3d4389318fe28a0c8c54/testing/marionette/harness/marionette_harness/tests/unit/test_window_handles_content.py#92

The test might be so fast that even the empty page hasn't been loaded yet into the second tab. It looks like when accessing the current URL we should always run Wait().until().
