Menu Bar disappeared

[LorenzoMorelli]

OS
Arch Linux x86_64

Gmail Desktop Version
3.0.0-alpha.35(stable)

Describe the bug
The title panel is neither visible nor clickable anymore

Steps to reproduce the behavior

1. Go to Preferences -> Set title bar style -> System
2. Go to Preferences -> Hide Menu Bar
3. Click on Full Refresh (I think it should happen even if the application is restarted)

Expected behavior
I would aspect that the Gmail view shift down when I click ALT in order to let me see the app settings, commands etc...

Media

As you can see in the screenshot when I click ALT it shows up a little rectangle of the settings panel (I think at least it is) but it is neither fully visible nor clickable

Additional context
Thank you for your work, you are doing a great job with this app!
