Expected Behavior

If a favicon download can't be completed for a determined period of time, it should be terminated and an error message should be displayed.

Current Behavior

When I click "Download favicon", nothing happens and the button stays grayed out permanently for all entries until I restart KeePassXC. After the bug occurs, the "X" button doesn't actually close the program, KeePassXC keeps running in the background so I have to kill the process from the task manager in order to restart it (single instance option is enabled).

The bug only occurs for one particular website and it happens every time I try, whether the "Use Google as fallback for downloading website icons" option is enabled or not. I can download the websites favicon (https://www.gittigidiyor.com/favicon.ico) and add it to the entry manually without problem.

Steps to Reproduce (for bugs)

1. Create a new entry for "https://www.gittigidiyor.com/".
2. Click "Download favicon" button.
