Gtk+ does have code that tries to resize a window if it did not get the size it requested.
Also, it does try to satisfy the size hints itself, which is wrong.  Hints are for the window manager to respect or ignore as it wishes.  It is nothing wrong with ignoring hints.  They are, after all, just that, hints.
This is an example why it doesn't work to do what Gtk+ does.  This is a major Gtk+ bug IMHO.
I'm afraid it is out of Emacs control.
