Email then password login flows

Some websites on mobile have a login flow with two stages, first email … continue … then password … submit.

Examples include
etsy.com (mobile)
wayfair.com (web)

I use multiple different emails and rely on a password manager for not just the password but the email I happened to use as well. How should I interact with bitwarden in this case. I have no autofill options on the “email only” part of the login flow (autofill does work when both email & password are prompted simultaneously)

(I’ve reproduced this issue on Chrome & Safari)
