GLFW fullscreen canvas buffer issue

So when using GLFW it would seem that when I enter fullscreen from HTML side, using the pregenerated button I then check in cpp code for change in canvas size. So I can update the rendering buffer correctly and other properties I need. This is mainly when Im in windowed mode to check for resizing.
When entering fullscreen i encountered render buffer not updating to proper values, resulting in glfw rendering to half a screen, or being offset, generally just the wrong result.

Deprecated function ``emscripten_set_canvas_size`` seems to trigger the proper js functions to set the canvas size and trigger glfw window resize callbacks.
``emscripten_set_canvas_element_size`` seems to not trigger those.

Possibly related issue: #8590
