Prevent Search Form Resubmission upon hitting Back button in OJS3

When search returns some results, and you hit the Back button on your browser (here Chrome), you’re taken to this ugly Confirm Form Resubmission page:
Is there any way to bypass it and take the visitor back to the Search form directly?

Another forum has a whole bunch of proposed solutions, so perhaps someone could find the one that’s fitting for OJS3?

This should be as simple as changing the POST methods for the search form to GET methods. Conventionally, POST should be reserved for operations which change the data-state, and GET should be used for idempotent requests (like searches).

This change was proposed some time ago, and blocked at that time by another issue. That blocking issue has since been resolved.

I’ll add a pull request to that issue which resolves this for the default theme.
