Thanks Alex. In my test I was never preventing it, but the tab focus movement to the next component was not worked (I expected to always move forward, at least): for some reason, the internal focus target was not part of the FocusManager tab loop candidates. I saw that, in this case, the FocusManager does a second pass on candidates and stops on the *first* candidate "owning" the current focused element, which works with simple UIs but often produce incorrect results (e.g. when the component is in an Accordion). Maybe the FocusManager could at least use the *last* owning candidate (thus narrowing the search towards the tree leaf), instead of the first one?
