Global Shader Parameter Undefined Behavior in Editor

Issue description

When changing certain Global Shader Parameters (in this case, a mat4) in the Project Settings, the value sent to the editor 3D view appears to be undefined, resulting in garbage values sent to the shaders.

As an example here, I'm using a mat4 to describe global light directions for a lighting shader
Note that the shader receives a different value even when the editor is being set to the same values

Setting the global parameter from a script does pass the correct value to the shaders

I have also determined the shaders in the editor also do not get correct values from the project.godot when loading the project.

Steps to reproduce

• Create a Global Shader Parameter of mat4 type (Project > Project Settings... > Shader Globals)
• Create a shader that visualizes the value of the mat4 (global uniform mat4 global_mat)
• Attempt to modify the global in the same Project Settings menu, the shader will receive garbage values
