Highlight of an expanded drop-down menu closes the menu area

Hello,
In sikuli rc3 it was noticed that, after clicking upon a drop-down button, then highlighting the expanded menu area, the highlight execution seems to close the expanded drop-down menu.

This behavior was not present in rc2, where it was possible to highlight an expanded drop-down menu (this is the desired behavior).

Would it be possible to have the highlight behavior upon an expanded drop down menu maintain the menu expanded during and after highlight execution? (in rc3)

Thanks,
