cursor is drawn outside view when scrolling on mobile Safari

[JannemanDev]

1. Goto https://codemirror.net/6/examples/zebra/
2. place cursor on first line
3. scroll the view down to bottom line

you will notice that the cursor is drawn outside view when scrolling

Update: use a mobile browser for example on iPad or iPhone.

Cannot reproduce in Chrome in Linux. What is your browser and OS?

Can't reproduce on Firefox / Linux either.

If this is Mobile Safari, yes it does that, and there's no known solution to it. Otherwise, yes, please provide a bit more information.

Sorry I forgot to mention my platform: I used Safari, but it also happened on Firefox and Chrome, all on my iPad and iPhone.

In screenshot below I had put the cursor on the first line and scrolled some lines down.

Btw: I also tried Ace Editor and when you open http://ajaxorg.github.io/ace-builds/demo/scrollable-page.html on your mobile browser and do the same steps as mentioned above, it does work (on all mobile browsers). So some way some how it is possible :)

I also tried Ace Editor

That doesn't use the native cursor, so that's a different story.

Those, due to Apple's bizarre platform rules, all using the same rendering engine.
