Modal mouse wheel issues in Chrome on Windows/Linux

Created by: NerdGGuy

A modal is loaded on window.onload with the windows height smaller then the modal content. Scroll bar exists but mouse wheel doesn't scroll when using Chromium Version 41.0.2272.76 Ubuntu 14.04 (64-bit). Also confirmed this issue exists on Chrome Version 42.0.2311.90 Windows. Mouse wheel seems to work in Firefox.

Re-sizing the window restores mouse wheel functionality. Also weirdly if a close button exists on the modal (not in this case sorry) mousedown on the button then mouseup away from button also restores mouse wheel functionality.
