Steps to reproduce

Both IE 11 and Edge ignore values assigned to the WebGL vertex shader’s gl_PointSize variable when using gl.drawElements. When using gl.drawArrays, the points are rendered correctly.

I created a minimal example showing the issue here: http://tsherif.github.io/ie-edge-pointsize-bug/

The two canvases should render identically, but the one on the right, which is drawn with gl.drawElements, ignores the fact that gl_PointSize was set to 10.

Browser versions used:
Edge 25.10586.0.0
IE 11.212.10586.0
