Focus navigation is trapped from DropDownList tools

[mbechev]

Description

The focus is trapped from the DropDownList tools when the focus is directly returned to the tool which prevents navigating to any other tool with arrow keys.

Steps To Reproduce

1. Use Shift + Tab to navigate from Editor content to Toolbar.
2. Navigate to any DropDownList and select any option from it.
3. Use Tab to focus back the content area.
4. Repeat step 1 which will focus the last used DropDownList tool. Arrow keys no longer focus the previous or next tool.
