Mouse wheel scrolling is reversed on web version

[Weeppiko]

Both mouse() API and the editors are affected by this issue

This is a duplicate of #713 but that's closed even though it's still an issue

Can't reproduce it in chrome based browsers, but saw it some time ago on other versions and still think it's a SDL2 lib issue, not a TIC-80 issue.

i am on ubuntu, can reproduce on both chromium and firefox, most current versions.

my system setting is traditional scrolling, which tic80 locally respects. on both chromium and firefox the webplayer scolling is apple-style/"natural", that is reversed from my system settings.

@Weeppiko @ChildishGiant Which native platform is your browser running on? I wonder if this is limited to Linux, etc...

0.80.1344 on tic80.com Chromium (Including new edge) & Firefox Windows 10

I have a run a dual boot and various browsers and have always noticed this. I can try to replicate again soon.

I tested this on two Linux machines: In Chromium, scrolling works as expected. In Firefox, scrolling is reversed.

I still think this is a sdl2 library bug, but we could find a workaround on the JS side.
