Bank upgrade, autofill not working

I'm not sure if this is the correct place to ask this, but my bank recently updated their online banking experience, and 1Password isn't able to correctly autofill the login/password fields. When it tries, the fields are blanked out, but still marked as filled by 1P (the `data-com-onepassword-filled="light"` attribute is set). I can still copy & paste the values.
