Saka key stops global keyup events to the page

When Saka key is active, the page no longer receives keyup events on the document or window object.

Minimal Reproduction:

window.addEventListener('keyup', event => {
  console.log('window keyup', event.key)
})

document.addEventListener('keyup', event => {
  console.log('document keyup', event.key)
})

Here is a jsbin demonstrating the problem: https://jsbin.com/nipijeh/edit?js,console,output

I understand that Saka key might have to block keys which it has its own keybindings mapped to but keys that are "Saka free" (like Tab) should still be forwarded.

This is a replacement for issue #153, I decided to create a new one as the problem is bigger and more focused.
