### Electron Version

14.0.0-beta.18

### What operating system are you using?

Other Linux

### Operating System Version

Fedora 34

### What arch are you using?

x64

### Last Known Working Electron version

13.1.8

### Expected Behavior

Frameless windows should have mouse interaction, similar to regular windows.

### Actual Behavior

Every single regular mouse event is completely ignored, on all levels thinkable. Selection doesn't work, double-clicking doesn't, input fields don't work, and even custom events on the window/body don't fire at all.. The keyboard does work as expected, so the app is not frozen and hasn't crashed.

### Testcase Gist URL

_No response_

### Additional Information

No gist needed, just add `"frame": false` to any basic electron app to break all mouse functionality when using the latest beta.
