User Agent: Mozilla/5.0 (Windows NT 6.1; Win64; x64; rv:69.0) Gecko/20100101 Firefox/69.0

Steps to reproduce:

• Windows 10, Wacom Tablet (tested with Bamboo and Intuos 4)
• Open: https://bitbof.com/stuff/mouse-vs-pointer.html (similar behavior is to be observed on almost all drawing sites, or sites that use drawing widgets)
• click "init with mouse-events"
• draw a smiley with the pen

Actual results:

• the drawing is all messed up

Expected results:

• you should see a smileyface

It works when you press "init with pointer-events" and then draw, or use another browser.

This breaks almost all drawing sites. They can't really switch over to pointer events, because Firefox has a lot of bugs with that too. It used to be great in the past, but currenty Firefox is very broken for stylus users.
