User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/67.0.3396.87 Safari/537.36

Steps to reproduce:

Open the attached HTML document and open the console. Click in the console. Then click in the cyan span within the editing host.


Actual results:

The selection change event fires before the focus events.


Expected results:

The selectionchange event should have fired after the focus events, just like any other time focus causes selectionchange.

[manavm]

document.addEventListener('selectionchange', () => {
  console.log(document.getSelection());
  console.log("hi");
  console.log(window.getSelection());
});

Pasted the above code in the browser console in FF and in Chrome. Works as expected in Chrome where any sort of highlighting by clicking and dragging triggers the event. Nothing whatsoever in FF. :(
