Revert "[Identity Pill] Don't freeze the animation during password bubble"

This reverts commit 896db5d1.

Reason for revert:
as this is intended to be cherry-picked on beta, we want to
minimize risks.
After discussion we decided to go for an even smaller change, to
be extra safe.

Original change's description:
> [Identity Pill] Don't freeze the animation during password bubble
> 
> This CL reverses part of the change introduced in:
> https://chromium-review.googlesource.com/c/chromium/src/+/1826678
> 
> The reason is that we don't want the pill to stay open while the
> password bubble is displayed, as the user may mistakenly believe that
> their password is uploaded to their google account.
