    <thetext>The &quot;overflow&quot; event is non-standard: https://developer.mozilla.org/en-US/docs/Web/API/Element/overflow_event yet we have code for it (see OverflowEventDispatcher).

caniuse.com says we don&apos;t support it: https://caniuse.com/mdn-api_element_overflow_event

so that&apos;s confusing.</thetext>
