This may be related to bug #47611 or could be a jquery bug as it is using jquery's .height(newHeight) method. Tested on: chromium 15.0.874.121 on gentoo. chrome 16.0.912.63 on mac os x 10.7 lion. safari 5.1.2 (7534.52.7) on mac os x 10.7 lion. will have access to windows machine on Jan 3, 2012 for further testing. When zoomed in (not pinch zoomed in Safari) like via Command++/Ctrl++, jquery set height does not set the height correctly. See http://eternalsword.com/webkitbug/zoom-set-height-test.html for testing and how the test works. Problem does not seem to be exhibited when zoom factor is < 100%, only > 100%. Has not been tested on any version of msie, but the test works properly on these tested browsers: firefox 10beta2 on mac os x 10.7 lion opera 9.5 on mac os x 10.7 lion opera 11.60 on mac os x 10.7 lion opera 11.52 on gentoo firefox 9 on gentoo
tested on webkit nightly as well on mac os x 10.7 lion and the issue is still exhibited. I have a workaround method for any developers frustrated by this that can be located at http://eternalsword.com/webkitbug/zoom-set-height-workaround.html
