AutoFill does not always fill in Firefox

[keepassium]

Describe the bug When AutoFill is used in Firefox for iOS, the selected entry is not always filled in the forms.

In particular, this happens when AutoFill shows the keyboard (either for unlocking or for search) and does not show the biometric scan prompt.

When the biometric scan prompt is shown, everything works as expected regardless of keyboard.

To Reproduce Steps to reproduce the behavior:

1. Open any login form in Firefox, then open KeePassium AutoFill
2. Unlock the database by entering the master password
3. Select an entry
4. AutoFill closes, but login form remains empty

Expected behavior The login form should be filled with the selected credentials.

Workaround Turn on biometric app protection (settings → App Protection → Use Face ID/Touch ID).

User Information (please complete the following information):

• Device: iPhone 11
• OS: 13.6
• App Version: 1.14.69
