reverseDepthBuffer: true broken since r170 (works in r169)

[haxiomic]

Description

reverseDepthBuffer: true should set WebGL to use reversed depth which gives better precision near camera

This worked as of r169 but is broken in r170

reverseDepthBuffer was added in r169 by @CodyJasonBennett
#29445
#29461

And iterated on in r170
#29579

Reproduction steps

1. new WebGLRenderer({ reversedDepthBuffer: true })
2. Add anything to the scene
3. Notice nothing renders unless reversedDepthBuffer set to false

Code

new WebGLRenderer({ reversedDepthBuffer: true })

Live example

Showing all versions from 169 to 174, notice only 169 shows anything

Fixed by @prideout's workaround

renderer.getContext().clearDepth(0)

I will make a PR when I get time
