I can reproduce the issue on Nightly74.0a1 Windows10, but not on Chrome80 dev.

As far as I've tested, no input event is fired at running the script that means that setUserInput is not used. So, it's restored without autocomplete etc. I guess cache does it?

State restoration is purely in the DOM not in cache.
We used to create a new SHEntry on document.open, so the new load did not have a layout history state. Now we don't do that, but should probably just clear the state out explicitly on document.open.

Otherwise we're using state from the pre-open document for whatever content is
being written, which is not likely to be right.
