Vertical setting ignored on floating toolbar

Continuing the discussion from How can I NOT center button labels on a floating toolbar set to vertical?:

In version 13.14.2 beta I noticed that enabling the vertical option or using the following command is showing the toolbar in a horizontal layout instead of the expected vertical layout. In other words, the Vertical option is not always working.

Toolbar "MyTestToolbar" FLOAT=vertical 

That option changes how things are laid out (e.g. the buttons go into columns that are the same width). You still have to resize the toolbar to get things to all be in a single column if that's what you want.
