Open and fill only works immediately after unlocking

Hey froghammer and @SpaceSwift 👋

Thanks for giving the early access a try! I was able to reproduce the issue you mentioned, and I'm having a lot of trouble finding a pattern on what will fill vs. what won't fill as well. I've got this reported to our development team. For now, you should be able to visit a website, then use the inline menu (directly underneath the field) to fill your credentials. Would you mind double checking that filling within the browser is working for you? I just want to make sure you've got a way to get your credentials to the form. :)
