(Core :: DOM: Copy & Paste and Drag & Drop, defect)

Description

Attachment: bug-reproduction.mp4

User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/136.0.0.0 Safari/537.36

Steps to reproduce:

1. Add draggable="true" to a button element (to make it draggable)
2. Add a visible ::before pseudo element to the button
3. You cannot drag the button from the ::before element (and no "dragstart" event is fired)

Standalone reproduction case: https://pvyscd.csb.app/
Reproduction case with code: https://codesandbox.io/p/sandbox/pvyscd

Actual results:

No drag is started when trying to drag from the ::before

Expected results:

The draggable button should have been dragged when dragging from it's ::before

The Bugbug bot thinks this bug should belong to the 'Core::DOM: Copy & Paste and Drag & Drop' component, and is moving the bug to that component. Please correct in case you think the bot is wrong.

Edgar, would you agree that it's a dupe of bug 568313? (I'm asking because you've dupe a bunch of other bugs to that)
