[Solution] Added non-passive event listener warning in Chrome

[usersina]

This warning can simply be fixed, as of version 5.62.0 by changing the line 536 in codemirror/lib/codemirror.js

From

emitter.addEventListener(type, f, false);

To

emitter.addEventListener(type, f, {passive: false});

Will that not cause IE to set useCapture to true for the listener?

would be great if it can be fixed message in console:

[Violation] Added non-passive event listener to a scroll-blocking event. Consider marking event handler as 'passive' to make the page more responsive. See
