iPad scroll zoom issue

[RedAuburn]

I am unable to scroll-zoom when using an iPad with a dedicated mouse or magic keyboard trackpad. The issue happens on both the embedded version of iD on osm.org, and on http://ideditor.netlify.app/

Tried Firefox and Safari, it happened on both

Hi @endim8!
Which version of os is your iPad using?

[RedAuburn]

iPadOS 15 Beta 3, although it's been happening at least since 14.6 (I only got my iPad recently, so I haven't tried before 14.6)

I've sold my iPad so can't test this specific issue anymore, however I was having a similar issue on my MacBook that replaced it.
After looking at #5550 and then webcompat/web-bugs#73148, It seems that setting dom.event.wheel-deltaMode-lines.disabled to false in Firefox's about:config fixes it

For reference: #5492,

Issue: delta y value for both 2 finger panning and mouse scroll on mac os mozila firefox was always integer and therefore mouse scroll was being treated as 2 finger panning mode.
Solution implemented: Remove 2 finger panning handling for mac os firefox as map zoom in/out is of higher importance.

The scrolling in Safari on iPad, seen in the original video, looks more like #7576 than #5550 or webcompat/web-bugs#73148.
