After applying then removing the display value of 'none' to an iframe, mouse scrolling doesn't work. Once focus is given to the iframe the frame can be navigated with keyboard controls, but mouse scrolling remains nonfunctional. Workaround : changing the size of the frame restores correct behavior. A test case has been provided in the attached file.
