Select: Dropdown does not show when widget is inside an overflow:hidden container

[tomdye]

Bug

When the select is placed within a container which is using overflow: hidden (Toolbar for instance) the select drop down renders inside the parent rather than floating above and is not visible. Furthermore, it appears to break the flow / layout of other elements in the container.

This bug is not present when using the native select option.

This is blocked by framework change to add body portal

@tomdye Is this still blocked, now that dojo/framework#448 has landed?

[tomdye]

@mwistrand this is fixed now by the new select, combobox will be replaced with the upcoming typeahead.
