Problem with Keyboard Shortcuts on iPadOS

Editor does not capture `cmd + S` on iPadOS at first attempt. `alt + H` is not captured at all, since it generates `^` at least on Turkish Smart Keyboard. `shift + Enter`, `alt + W`, `cmd + Enter` combinations work as expected.

### What I Did

I hit `cmd + S` key combination.

### What I Expected

As soon as I hit the combination, a save of notebook to appear in History.

### What Happened

I have to hit `cmd + S` many (many) times to save the notebook, otherwise not functioning.

### A Note on Monaco Editor

On iPadOS, https://github.com/cdr/code-server (a modification of VS Code to make it run in browser) captures shortcuts that are not pre-occupied by iPadOS itself correctly as intended.
