C# GD.Randf() breaks HTML build

[VoidGoat]

Godot version:

v3.2.2.stable.mono

OS/device including version:

macOS 10.15.4 exporting to HTML

Issue description:

Using GD.Randf in a C# script makes HTML build freeze on launch. Removing the script or the GD.Randf call fixes the problem.

Steps to reproduce:
Create a scene and add a script to a node with a script that calls GD.Randf() in the _Ready() function. Something like
GD.Print(GD.Randf())
Then export the project to HTML. When the HTML project is run from a web server it starts to load but freezes.
