A mousedown event on the resize corner of an element with e.g. `resize: both` can be used to know that a resizing operation has started. In Chrome and Firefox, the mousedown is fired normally when you start resizing the element. In Safari, there is no mousedown event ever.
See https://jsfiddle.net/7dygb36k/11/
If you click inside the element, it logs "mousedown", "mouseup", "click" as expected
If you click on the resize corner, it logs "mouseup", "click"

Seems pretty clear from the code here https://github.com/WebKit/WebKit/blob/931edb0a5a560a009a8ca6a23f39aa4bff6d6a5a/Source/WebCore/page/EventHandler.cpp#L1900-L1915 that mousedown is not fired
