[BUG] - Two instances of same app always show preview of the first instance

[jonn-set]

Describe the bug

I have 2 installations of Firefox on my machine running on 2 different profiles, one if called Firefox and other Firefox 2.

When both instances are open, it will always show previews of the first open instance.

I tried changing the CFBundleName inside info.plist of Firefox 2.app to 'Firefox 2' and is recognised separately by DockDoor in its Settings->Filter page, but when it comes to showing the preview it always shows the Firefox window, if its open.

Steps to reproduce

• Install 2 copies of any app you like, in my case I have Firefox installed twice with different name
• Open both copies
• Hover the mouse over both instances, the window will only show the first instance's windows in preview

Expected behavior

Either combine open windows from both instances into one or show them separately

Actual behavior

Always shows the first instance window preview
