(Keywords: regression, reproducible)

User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.15; rv:70.0) Gecko/20100101 Firefox/70.0

Steps to reproduce:

  1. Go to https://www.tagesschau.de/
  2. Click on a video on the top, e.g. "100 Sekunden" to open the video page
  3. When the page is open press the back button

Actual results:

Firefox creates an additional history item for the page and the back button only shows the video page with the video removed

Expected results:

Does not create additional history item and moves back to https://www.tagesschau.de/

(Works in Safari, Chrome, and used to in Firefox.)

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.
