Issue description

Changing the Boot Splash background color does not reflect in the web export. I even tried to Run directly from the Editor but same result. (Run in Browser).
or Export Web build and Check Background

Steps to reproduce

Project Settings -> Application -> Boot Splash -> BG Color -> Set any Color
This change project.godot -> boot_splash/bg_color=Color(1, 0, 0, 1)

Run directly from Editor but same result.

Minimal reproduction project (MRP)

At this point, the HTML template changed in 4.3 only supports boot splash image. Expansion to include more parameters from the application/boot_splash setting will require adding more variables passed during export.

For now, I can suggest changing the background using CSS style inside Head Include field, for example:

<style>
#status { background-color: red; }
</style>

or even more fancy:

<style>
#status { background: radial-gradient(circle, rgba(15,15,121,1) 0%, rgba(25,224,56,1) 100%); }
</style>
