App menu is hiding when it should not

[stychos]

Description of the bug

When I use Sublime Text with the menu hidden by default (which I prefer), I previously had the ability to hid it and call by pressing Alt button. Then, more than for a decade I used mac and didn't suffer because of it, awe to the macOS global menu. Now, when hackintosh is dying I turned back to Linux and really suffer when I see this menu line - it takes too much vertical space that must be in the top bar. Which is not, unfortunately, thanks the Linux way of things. So I keep it hid by default and wish to be toggled by pressing Alt, which worked fine a decade ago on Windows. Now, when I press Alt it shows first menu subtree fine, but when I try to use another one, it hids.

Steps to reproduce

1. Open Palette, toggle menu off,
2. Press Alt to show menu, File menu will be shown,
3. Try to move mouse cursor to any other subtree, like Preferences - menu will hid before you can select anything.

Expected behavior

Should be able to use any menu subtree.

Actual behavior

Can use only File menu subtree.
