Mousewheel font sizing needs to be disabled on elements where ctrl is used for multiple selection (since it's easy to trigger the font resizing by mistake).

This is pretty simplistic - it disables ctrl+mousewheel resizing on form controls and XUL content. I think it's reasonable though. There are obvious problems with doing the resizing for form controls, and it would be unexpected (to say the least) for the chrome text to zoom. We may want to let content-area XUL do text zoom at some point, but that seems like an edge case.

This bug doesn't seem to be fixed (anymore?). Steps to reproduce: 1) go to http://bugzilla.mozilla.org/show_bug.cgi?id=64908 2) click an email address in the CC list 3) with the intention of selecting another address, press Ctrl, hold, and use scroll wheel to reach the last email address in the list. What happens: text zoom increases. (Assuming that you have Ctrl+mousewheel set to do that.) What should happen: the CC <select> should scroll. Using Mozilla build 2004030208 on Linux.
