This test requires a gamepad device to be connected. Please interact with
the gamepad for it to be recognized. The "Trigger rumble!" button will be
enabled after that.
</p>
<p>
After pressing the "Trigger rumble!" button below, you should expect to
feel a localized vibration in both triggers of all connected
trigger-rumble compatible gamepads for one second.
</p>
<p>
Please press the "Confirm effect has played" button to conclude
the test.
