`selectionchange` fires differently across the browser engines #332

Closed mozesstumpf closed 3 months ago

mozesstumpf commented 3 months ago

During a code execution, the Selection API's boundary-points can change multiple times. For example:

const sel = getSelection();
...
sel.removeAllRanges();
sel.addRange(range1);
...
sel.removeAllRanges();
sel.addRange(range2)

The spec does not specify how many times the selectionchange event should fire if we change the selection multiple times before the macrotask queue gets executed.

Demo to reproduce: https://codepen.io/IDontHaveAny/pen/OJemybj

In Chromium and WebKit, the selectionchange fires multiple times, even though the Selecion will be the same by the time it gets executed. In Gecko, it fires once.
