GuiSearch: prevent Tab key to switch to work area (part of #12170)

QWidget::focusNextPrevChild() passes over to the parent (which is the
work area here) if the current window is not a dialog (isWindow()) or
a sub-window (window flag Qt::SubWindow).

We set the latter here to prevent this unwanted behavior.

Let's see if there are side-effects.
