See for example:

Test failures are listed as 

RobustResourceInitTest.MaskedStencilClear/ES2_D3D9 (status NOTRUN)
CopyTextureTest.CopyTextureRGBAToRGBAUnmultiplyAlpha/ES2_OPENGL (status NOTRUN)
WebGLCompatibilityTest.EnableExtensionEGLImage/ES3_OPENGL (status NOTRUN)
CopyTextureTest.CopyTextureBGRAToRGBPremultiplyAlphaUnmultiplyAlpha/ES2_D3D9 (status NOTRUN)

Instead of 

RobustResourceInitTest.MaskedStencilClear/ES2_D3D9 (status NOTRUN)
CopyTextureTest.CopyTextureRGBAToRGBAUnmultiplyAlpha/ES2_OPENGL (status NOTRUN)
WebGLCompatibilityTest.EnableExtensionEGLImage/ES3_OPENGL (status NOTRUN)
CopyTextureTest.CopyTextureBGRAToRGBPremultiplyAlphaUnmultiplyAlpha/ES2_D3D9 (status NOTRUN)

This may be breaking a Chrome extension I'm using for helping analyze test failures. Milo owners, could you help find an owner to fix this? It might be related to a recent change to add the status (NOTRUN, etc) to the test result.
