yubikey passkey auto fails on samsung devices

Here is a "story": 1. I want to sign in into github using a passkey stored on my yubikey 2. I plug in my yubikey 5C into my phone (samsung z flip 6) 3. I open github.com in firefox 4. I press "sign in with a passkey" 5. Firefox opens some samsung chooser, I choose "other devices > show qr code" 6. login fails and firefox opens Google's prompt to enter pin for the yubikey (but the login already failed, so it does not matter) My roommate experiences the same bug with his yubikey and his samsung S24. Doing the same in chrome works. Instead of opening samsung thing it opens Google thing directly where I can choose "use a different device" and it works after that (no login fail). Is this a known issue? Can I do something to fix it or at least debug it? (images are, in order, "prompt when using 'sign in with a passkey' in firefox", "login fails as soon as I tap 'show QR code'", and "prompt when using 'sign in with a passkey' in chrome)
