UI - Block "ignoring" using space

There’s no setting for this at the moment, but you could intercept the keydown event and stop it from propagating if it’s the space bar. For example:

document.querySelector('#root').addEventListener('keydown', function(event) {
    if (event.keyCode === 32) {  // key code for "space"
        event.stopPropagation()
    }
})

This stops the key event from propagating to the parent containers – i.e. the document.body, which the other keydown listeners are attached to.
