Bug 223350

https://www.khronos.org/registry/webgl/sdk/tests/conformance2/renderbuffers/multisampled-depth-renderbuffer-initialization.html?webglVersion=2&quiet=0&quick=1 Verify multisampled depth renderbuffers are initialized to 1.0 before being read in WebGL On success, you will see a series of "PASS" messages, followed by "TEST COMPLETE". Test renderbufferStorageMultisample with webgl1's DEPTH_STENCIL.
