Configuration dialog stuck after Default Client Secret field is filled

[sn50]

Describe the bug When entering custom OAuth credentials in Configuration > Options and Defaults dialog, after filling in the Default Client Secret field (by copy paste), the dialog is stuck and cannot be finished in any other means other than the X in the top right corner. I was not able to confirm the changes, thus was unable to use the credentials for new database.

To Reproduce Steps to reproduce the behavior:

1. Go to dialog Configuration, part Options and Defaults.
2. Enable enterring the custom credetials.
3. Insert the client ID.
4. Insert the client secret.
5. Clicking OK will do nothing. Clicking checkboxes inside dialog will do nothing.

Expected behavior I should be able to confirm, or change anything in the dialog after inserting the client secret.

Please provide the following information:

• OS, including version and build numbers: [Microsoft Windows 11 Home, 10.0.22631 Build 22631]
• Plugin Version [4.1.0.0]
• KeePass Version [2.57.1]
• "Normal" KP installation
• plugins: keepasshttp 1.8.4.2

Additional context I was able to insert custom OAuth credentials on the first tab of the dialog, so I can use the token for update of the existing database - hence it is not a blocker for me.
