PopupMenu positioned incorrectly when opened with the keyboard

[simonjb]

To reproduce:

1. open dijit/tests/test_Menu.html
2. focus the text area containing the text "hello there!"
3. open the menu (on windows: shift-f10 or windows context menu key, on mac FF: ctrl-space)

Expected:

• menu to open just below and right of the top left corner of the text area

Actual (FF):

• menu opens at the top left corner of the browser window

Actual (IE):

• menu opens at the mouse cursor or not at all if the mouse cursor is positioned off the right or bottom edge of the browser window

Fixing this bug is especially important for zoomtext users.

OK, so the implication is that if you use the keyboard to open the menu, it should be placed relative to the currently focused node, rather than relative to the mouse position? I guess that makes sense. You should be able to get the currently focused node from FocusManager?.

[simonjb]

Yes, exactly. If the menu is opened via the keyboard, it should be placed relative to the currently focused node.
