Bug: clicking on anchor links and hitting back twice causes notebooks to go blank

Clicking on an anchor link in a notebook inserts two entries into the browser history instead of one. Pressing back in the browser a few times then causes the notebook to go blank. Possibly related to recent hash param changes?

Tested in Firefox, Chrome and Safari on macOS:


Confirmed. Thanks for the report! We are investigating.


@bgchen It was indeed related to the recent hash/querystring changes.

We’ve had to go back and implement the hash syncing in a bit more of a complicated fashion — but it should be working properly now.

Please let us know if you notice anything else!
