I can reproduce the issue on Nightly72.0a1 Windows10.
However, It is necessary to execute step 2 & 3 twice.

I thought this might be related to async history.* API changes, but the pref didn't affect to this.

I confirmed the regression range of comment #3.
maybe the culprit is Bug 1270059 and Bug 1522150.
