I would test that this works for input elements, too.

Of course you can try it, if you build a custom k6 binary from the code on the branch. Fill() for <input> elements has worked so far, and it already has a test at https://github.com/grafana/xk6-browser/blob/main/tests/locator_test.go#L99-L105 If you find any scenario that fails with this implementation, I would be happy to deal with it.

Thanks @ankur22, @inancgumus, and of course @bandorko 👏🏻

What does the process look like for getting this into the next k6 release? So I know what to expect.

It will be in the next version of k6 (v0.50.0) which should be released in the next couple of weeks 🤞
