MS Edge black screen and Render Path Presets

In the Endless runner sample when using the "Deferred" Render Path Preset i'm getting a black screen in MS Edge (v16.16299) browser and in the console log there is the following error:

 SystemImpl.hx:316: Could not initialize WebGL 2, falling back to WebGL.
kha.js (21332,3)

 SCRIPT5022: Error: Could not compile shader:
Shader compilation errors
(2, 1): Required extension GL_EXT_draw_buffers is not supported
(2, 41): Internal compiler error
kha.js (39494,3)

switching to "Forward" render path gives the following error:

SystemImpl.hx:316: Could not initialize WebGL 2, falling back to WebGL.
SCRIPT5022: Error: Could not compile shader:
Shader compilation errors
(2, 1): Required extension GL_EXT_shader_texture_lod is not supported
(2, 47): Internal compiler error
kha.js (39617,4)

disabling "Generate radiance textures" option, gives the following error:

SystemImpl.hx:316: Could not initialize WebGL 2, falling back to WebGL.
kha.js (21463,3)

 SCRIPT5022: Error: Could not compile shader:
Shader compilation errors
(36, 22): Incompatible index expression. For non-uniforms, the index must be an expression formed of the loop_index and integer constants. For uniforms, the index must be an integer constant.
kha.js (39616,3)

switching to "Low" render path preset (with radiance textures off) seems to work (!!!) but i get the following warning:

SystemImpl.hx:316: Could not initialize WebGL 2, falling back to WebGL.
kha.js (21205,3)

6 WEBGL11157: INVALID_OPERATION: texImage2D: Invalid texture target and format combination
kha.js (37256,6)

[Request]

Could you please make change the "Low" render path to have "Generate radiance textures" OFF by default?

thanks.
