Steps to reproduce

On https://develop.element.io/#/login form I can't jump to "Password" button using keyboard "Tab" key, after I've filled the "Username" button, when I press "Tab" - spinner is coming and takes away the focus from password field, here is screencast:

Same problem is when I try to autofill the username and password, using some password manager (eg Bitwarden).

Outcome

What did you expect?

I expect to fill password via standard way.

What happened instead?

I need to use a mouse to set focus to Password input field.
