UI issues when accepting an invite

I was watching a user accept an invite and witnessed a couple oddities that would be worth fixing. I didn't try to repro them again, so not sure if they were flukes, but worth checking the next time someone is working in here.

1. Clicking into the empty password field didn't automatically pop up the suggest password dropdown. I was able to right-click where I found the option to "Suggest password", but it was odd that it didn't open when clicking into the input once like most other websites.
2. When clicking the yellow submit button to create the account (after entering a password), a red dot (I think it was a dot?) appeared below the input, making it look like there was an issue with password validation (but with no text displayed). But after the form processed, it correctly went to the email verification screen. So, just looks like something is up with the password validation on the UI side.

No file, test, or entry point is named. Start by reproducing the invite-acceptance flow and inspect the password field and form-validation behavior; done means both reported UI symptoms are understood and the account-creation flow behaves correctly without a misleading validation indicator.
