qBittorrent version and Operating System

qBittorrent 4.2.5
macOS Catalina 10.15.4

What is the problem

Two small bugs:

1. Pressing ⌘Command-W with the About window in focus closes the main application window.
2. It is possible to move the main application window in front of the About window. After that, clicking qBittorrent → About qBittorrent appears to have no effect.

What is the expected behavior

1. Pressing ⌘Command-W with the About window in the foreground should close the About window (just like clicking its Close button).
2. Clicking qBittorrent → About qBittorrent should bring the About window back to the foreground if it already exists.

Maybe make that window into a modal dialog? The Preferences and Check for Updates windows already are.

Steps to reproduce

1. Click qBittorrent → About qBittorrent from the systemwide Menu Bar.

2. Press ⌘-W.

3. Click qBittorrent → About qBittorrent from the systemwide Menu Bar.

4. Click the main qBittorrent window and move it over the About window.

5. Click qBittorrent → About qBittorrent from the systemwide Menu Bar.
