PRF Extension does not work with filekey.app

• I have read the Wiki, searched the open issues, and still think this is a new bug.

Explain the problem clearly and succinctly:

Steps to reproduce:

1. Visit https://filekey.app/ on desktop
2. Click the Create button
3. Scan the QR code and use KeePassDX as the passkey provider

I get the error: "This passkey doesn't support PRF, which FileKey needs. You can remove the new 'FileKey' passkey in your device's passkey settings"

Describe what you expected to happen:

It works with Google Password Manager, though, so I suspect the error has something to do with the recently introduced PRF extension.

KeePassDX version:

4.5.4 (Google Play version)

Build:

Free

Database version:

v2

File provider (content:// URI)

No response

Android version:

16

Android device:

oneplus 12

Additional context:

On desktop I have Google Chrome 53.0.8010.37 and macOS 26.6.2
