My only gripe is filling in card details, there is never a floating icon to click to do it automatically, you need to go to the menu bar and select the card.
Apart from that all perfect!
At one point I became convinced that this is actually a security feature. If I recall, an article demonstrated tricking users into entering their master password using those "in-browser" decorations. I could write some html/js to build your password manager icon/etc and trick you into thinking I'm your password manager? I now accept it as a necessary UX chore to leave the browser page, but would be interested in being wrong.
One of the things I used to store in LP was AWS IAM creds. Sure, you can store it in a Bitwarden "secure note" but it sure was convenient to have a defined format for it.
