The page header wraps its action group onto another line when the title and the
actions no longer fit together, so the title keeps its width and the actions keep
their labels on one line. The information button follows the subtitle text
instead of a flex row, which keeps it beside the copy at every width.
Cover the header in the plugin-manager browser scenario: the action group stays
inline when it fits, moves below when it does not, keeps its labels on one line,
stays inside the header, and retains focus across the change.
