Use pointerevents in Web editor

[osnr]

so drag works on iPad

@osnr just pushed a commit switching to pointerup & pointermove. In my simulator on my laptop I'm only able to drag the editor a little bit on mobile ... can you check on folk0 using your phone next time you're in?

I tried it at home on my iPad -- it seems like we need to stop the event propagating so it doesn't try to scroll the browser when you drag?

[osnr]

I can drag left and right but up and down don't work bc it goes to scrolling instead
