This does nothing. The fix is to ignore the current keyboard state and pretend the only key being held down is Space.

Click on the three dots to the far right of the English entry (or whatever language you're using) and select “Language options”. Scroll down until you find “Add a keyboard”. From that button scroll through all the many, many layouts until you find “Swiss German”. Once you’ve added the keyboard you should see a button on the far right of the task bar to select the layout. The dead key for this bug is where the =/+ key is on the standard US keyboard, top row to the left of Backspace.
