Inconsistent blending behaviour between Windows and HTML5

[distantforest1]

Describe the bug
Hi I'm getting some inconsistent behaviour for the blending for the Windows build target and the debug electron build.

On the Electron Build:

On the Windows Build:

I've created a repro of the bug:

To Reproduce
Open this up in VS Code:
https://github.com/distantforest1/Shader-G2-blendingbug

• Press F5 to run the debug, it is blending properly
• Build with Ctrl-Shift-B on Windows (Full Build opengl/directX). It is not blending as expected.

** Additional context: **
It appears that in the windows build, if you change the blending mode, you need to recompile the pipeline?

Expected behavior
Not needing to recompile the pipeline for blend mode changes, or requiring a compile for the electron build (for consistency).
