This fix requires to be able to recognize whether Fl_Wayland_Window_Driver::resize() is called by a resize operation of an encompassing widget or not. To do that, private static int variable group_resize_depth_ is added to class Fl_Group and an accessor to this variable is added to class Fl_Window_Driver.

WHAT IS FLTK?
The Fast Light Tool Kit is a cross-platform C++ GUI toolkit for
UNIX®/Linux® (X11 or Wayland), Microsoft® Windows®, and macOS®.
FLTK provides modern GUI functionality without the bloat and
supports 3D graphics via OpenGL® and its built-in GLUT
emulation. It was originally developed by Mr. Bill Spitzak
and is currently maintained by a small group of developers
across the world with a central repository on GitHub.
