Test Case

Safari Version 10.1 (10603.1.30.0.34)

This is an intentional duplicate of 82558 from 2012 which was fixed in the same year, but I cannot re-open. New test case included here in-case it's any different.

If a native slider is disabled while the user is dragging, then other pointer events on the page will stop working from that point onward.

In the following example, drag the slider to either end where it will be disabled, then attempt to click the button to get the alert.

<!doctype html>

<script>

        const input = (that) => {
                if (Math.abs(that.value - 50) === 50) {
                        that.disabled = true;
                }
        };

</script>

<input type="range" oninput="input(this)">

<button onclick="alert('Click')">Click</button>
