Patch for r432.
Every time I want to add new scripts on the Event Sheet, the JS suddenly disappears. When clicked, it shows, but when we're done, it disappears, and nothing happens when we preview. Stucks here forever. Ashley
I got this on the Console

[Violation] Added non-passive event listener to a scroll-blocking 'wheel' event. Consider marking event handler as 'passive' to make the page more responsive. chromestatus.com/feature/5745543795965952
