Info: When using the mouse wheel to scrolls, there are pauses every few scroll units. Makes scrolling unusable.

Reproduce: Go to the CodeMirror demo site (https://codemirror.net/index.html) and add large enough text. Now, try scrolling with the mouse wheel. The bug should manifest.

Fix: The fix seems simple: set pointer-events "none" on CodeMirror-sizer. How did I figure this out? I guessed that Chrome was not able to target the parent "CodeMirror-scroll", thus causing scroll issues.

Please let me know if there is a better, less-hackish fix than this.

Thanks for figuring out a workaround! I've pushed an alternative, somewhat more complicated patch, since many CodeMirror setups rely on mouse interaction with the content actually hitting the elements in the editor (for example unfolding by clicking a fold marker).
