Summary

The WebGLContextEvent type has been defined in Khronos' WebGL specification
for a number of years, but it was not noticed until recently that in Blink,
this type is not exposed on web workers. (Most applications simply add an
event listener for the type, and do not look for its prototype in the
global scope.)

This is a simple fix to Blink's Web IDL for WebGLContextEvent, but is a web
exposed change.
