If called when already popped down, warnings would be issued due
to priv->grab_pointer being unexpectedly NULL, this would happen
in regular operation when selecting items in appears-as-list mode.
So both add a NULL check for priv->grab_pointer, and bail out early
if the popup window is already hidden.
And also explicitly remove pointer/keyboard grabs from the display.
Whenever the grab is reported lost, we should popdown the combobox, so that the
GDK_WINDOW_TEMP window is hidden and removed from the toplevel, as done with
the menu for example.
Leaving the GDK_WINDOW_TEMP window open when re-activating the application
triggers several issues in the win32 backend, due to restacking windows of the
non-toplevel group into the toplevel group:

If you want to get rounded corners on an hbox, instead of
:first-child {
border-top-left-radius: 5px;
border-bottom-left-radius: 5px;
}
:last-child {
border-top-right-radius: 5px;
border-bottom-right-radius: 5px;
}
you now need to write:
:first-child, :last-child:dir(rtl) {
border-top-left-radius: 5px;
border-bottom-left-radius: 5px;
}
:last-child, :first-child:dir(rtl)
{
border-top-right-radius: 5px;
border-bottom-right-radius: 5px;
}
Instead of using gtk_style_context_get_font() in
pango_context_get_metrics(), use pango_context_get_font_description().
The context contains the font description we are about to use after all.
Add an internal API that allows GtkStyleContext to create a widget path
for the widget and with that bypassing gtk_widget_get_path() and that
function caching the path.
When we're size allocating the children widgets, always trim the
allocation for padding and border of GtkComboBox, as that's all the area
they have available.
It was using the wrong padding values for RTL, and generally, using the
same variables in a distant macro makes this method even more
complicated than it already is...
If we're in menu mode with no children, instead of tweaking the
allocation of the arrow and the separator separately, tweak the
allocation of the box that contain both.
GtkComboBox always handles focus through its children, so there's no
need to request and allocate them again.
In fact, Adwaita was forcing these style properties to zero for
GtkComboBox.
