Because only the most specific hotkeys can be active at any time,
releasing a key may require re-activating less specific hotkeys.
There were two issues with this behaviour:
- It was buggy, as it only checked one active key, when any still active
key can trigger hotkeys.
- "HotkeyPress" and "HotkeyDown" events where sent, as if the hotkey was
pressed, which was unexpected for most code/users (it is unusual to have
a "Press" event on key release).
This fixes these issues by "silently" re-triggering the hotkeys in such
a case. It also makes it easier for JS code to use "hotkeyPress" instead
of "hotkeyDown" for non-continuous behaviour.
