<input id="readonlyNumber" type="number" onmouseup="mouseupEventOnReadonlyNumber()" />
<input id="disabledNumber" type="number" onmouseup="mouseupEventOnDisabledNumber()" />
<p>
This tests if the value of a number input form does not continue
to increase/decrease in the following scenario.<br/>
(1) Click the spin button of the input form.<br/>
(2) Hook the 'mouseup' event and disable the input form.<br/>
(3) Enable the input form after some delay.<br/>
To run this test manually, input any value in the input form
and then click the spin-down button.
At this point, click the spin-down button quickly and
do not move the cursor from the spin-down button after the click.
If the value decreases by just 1, this test passes.
