This only seems to reproduce for me on an actual device, not in the responsive design mode. But since the nightly builds of Firefox Preview effectively cannot be debugged right now until bug 1631012 lands, I'll have to wait for that first.

The issue no longer occurs, with ETP - Strict login is successfully performed.
