Works on all open Visual Studio instances at the same time

[MikelLuri]

Describe the bug
With several Visual Studio instances open, when scrolling on the tabs of one of them, all tab groups of all instances are expanded/collapsed.

To Reproduce
Steps to reproduce the behavior:

1. Open more than one Visual Studio instance
2. Open several documents in each, so that multiple tab lines are required to show all documents.
3. Scroll on the tabs
4. The tabs on all Visual Studio instances are shown as multiline

Expected behavior
Only the tabs on the current Visual Studio Instance are shown as multiline

Visual Studio settings are global affecting all instances (possibly synchronized across multiple machines). This extension cannot apply change only for single instance or single window/tab well in that instance.

But you can add suggestion (if not already added) to ticket here https://developercommunity.visualstudio.com/t/Scrollable-open-file-tabs-with-mouse-whe/353560, inside Visual Studio it could be implemented without these hacks.
