Describe the bug

Since updating to 4.11.1 from 4.10.5, I am unable to upload files by dragging and dropping them onto the window.

Reproduction

Drag and drop a file onto the chat window.

Expected behavior

The app should respond to the hovered file, and after dropping it, the file should be queued for upload in the chat.

Platform and versions

1. OS: Windows 11
2. Cinny version: 4.11.1 (desktop)

Additional context

No response
