When launching from legacy screen mode, new desktop mode context menu inaccessible

[shiftyscales]

Describe the bug

If launched in the legacy screen mode, the context menu is inaccessible in the new desktop mode. Pressing the middle mouse button produces exceptions.

To Reproduce

• Launch Neos in legacy screen mode
• Switch to the new desktop mode (F8)
• Attempt to open the context menu (MMB)

Expected behavior

The context menu remains accessible.

Bug information (please complete the following information):

• How often does it happen: Always
• Does the bug persist after restarting Neos? Yes
• Neos Version: 2021.3.23.263
• Neos Platform: Windows
• Regression: No

Additional context

This likely won't be relevant once the desktop mode is made official and replaces the current legacy desktop mode. If it's not a quick/easy fix, I don't see any specific value in it, and it shouldn't be prioritized/this issue can be closed. It's possibly as a result of legacy desktop mode quirks, e.g. the lack of a proper character controller/locomotions.

Using new desktop mode with the old one isn't supported.
