Make browser-prompted dialogue boxes unparented so that they appear on the current monitor.

Previously, they would be opened wherever the main window is. This could
easily be on a different virtual desktop (or workspace): if so, the dialogue
box would not be visible on any attached monitor until that workspace was
selected.

(This breaks some tests involving the database-open dialogue box.)
