master and also in 4.3.2.M20140221-1700

In the (WebKit) Browser widget on the Mac, KeyDown/Up events have a wrong stateMask when a modifier key is pressed/released. The pressed key should not be present in the stateMask, and the released key should be present.

(From Felipe Heidrich in bug 367379 comment #2)

This works fine in other SWT widgets (e.g. Text) and on Windows (IE browser).


I'm pretty sure this bug is the reason for the Platform UI test failures mentioned in bug 428631 comment 4 (but I can't explain why the test don't always fail -- probably some timing issue that prevents the welcome page from taking focus).

This bug hasn't had any activity in quite some time. Maybe the problem got resolved, was a duplicate of something else, or became less pressing for some reason - or maybe it's still relevant but just hasn't been looked at yet.

If you have further information on the current state of the bug, please add it. The information can be, for example, that the problem still occurs, that you still want the feature, that more information is needed, or that the bug is (for whatever reason) no longer relevant.
