Submenues in popup menues are broken in non-IE browsers

[martinkou]

To reproduce the bug:

1. Go to sample01.html with Firefox or Safari (Popup menues aren't working in Opera 9.50 build 9660 as of now).
2. Insert an empty table to the document.
3. Right click on the empty table.
4. Try to open any submenu (e.g. "Cell") by moving the mouse cursor.
5. The submenu appears, but the original menu disappears.

The bug is due to [1111], which was a fix to #1559.

Fixed with [1129].

My fault here.

Fortunately, a simpler solution can be found instead of [1129], which goes touching too much things for a pre-release change. I've reverted it with [1130], and proposed a new fix with [1131].
