Mousewheel scroll stopped working

NWJS Version : 0.35.1-sdk (I believe I saw it on 0.34.x versions as well) Operating System : Windows 10 x64

The issue: (using an app I’m writing) sometimes the “mousewheel scroll” stops working for no apparent reason. Scrolling the wheel on my mouse doesn’t do anything.

Some notes/debugging:

• I can still scroll using window.scrollTo()
• I can still scroll dragging the scrollbar
• manually adding a $(document).on('wheel', (e) => console.log(e)) does report wheel scrolls, but nw itself doesn’t seem to see or act on it. The document doesn’t scroll. It is not defaultPrevented either.
• I don’t use any kind of ‘wheel’ event modification in my code.
• I was able to fix it with a ‘wheel click’ (also know as middle-click) to scroll the document with only the mouse dragging. After that, the scroll wheel worked again.
• I do have a lot “dom-banging” (I believe it’s called that) in my app, using entire pages .show() and .hide(), as well as a fairly good amount of .append(), all using jQuery. Dunno if that’s relevant.

Steps to reproduce: sorry, no idea. It happens randomly, maybe once every 10 hours of using nwjs, or even every 20 hours. Not often though.

I think this is a Chromium issue, it happens quite frequently when using sites like Twitter. For some reason pressing the mouse wheel button fixes it but the cause is still unknown, as far as I know.
