Steps to reproduce the problem:
1. Open developer tools console and paste the following snippet:

window.ondrop = function (e) {
  console.log(e);
  debugger;
  e.preventDefault();
  e.stopPropagation();
}

or alternatively:

window.addEventListener('drop', function (e) {
  console.log(e);
  debugger;
  e.preventDefault();
  e.stopPropagation();
});

2. Drag and drop a file from a file manager (e.g. Nautilus on Linux)

What is the expected behavior?
I expect the console to show the event (Drag*) and to stop at the debugger. After stopping at the debugger, I expect the page to stay the same and not open the file within the browser (if it's an image) or "download" it if it's a non-openable file.

What went wrong?
The console does not log the event, the debugger does not get triggered, and the browser attempts to open the file.

Did this work before? N/A
