Focus traversal policy used for toolbar to modify traversal behaviour:
<ul>
<li>Tab-key moves focus out of toolbar.</li>
<li>If moving focus into the toolbar, focus recently focused toolbar button.</li>
</ul>
If the toolbar contains non-button components (e.g. combobox), then the behavior
is slightly different. Non-button component are always included in Tab-key traversal.
