Olivier Fourdan 83b54bab57 wayland: Fix a race condition with xdg_popup resize 
When resizing an xdg_popup immediately after the initial mapping, there
is a race condition between the client and the compositor which is
processing the initial size given by the xdg_positioner, leading to the
xdg_popup to be eventually of the wrong size.

Only way to make sure the size is correct in that case is to hide and
show the window again. Considering this occurs before the initial
configure is processed, it should not be noticeable.

/**
* gdk_wayland_window_set_transient_for_exported:
* @window: the #GdkWindow to make as transient
* @parent_handle_str: an exported handle for a surface
*
* Marks @window as transient for the surface to which the given
* @parent_handle_str refers. Typically, the handle will originate
* from a gdk_wayland_window_export_handle() call in another process.
*
* Note that this API depends on an unstable Wayland protocol,
* and thus may require changes in the future.
*
* Return value: %TRUE if the window has been marked as transient,
* %FALSE if an error occurred.
