WebGL uninformative errors

Unity Engine

While trying to build our game for webgl I encounter time to time different webgl only errors in runtime. For example, look at this error.

Error message

[Error] ArgumentOutOfRangeException: Argument is out of range.

This is from development build with fast and slow optimisation level (couldn’t make fastest optimisation level build).
And you see the problem. Somewhere in project I got ArgumentOutOfRangeException. And this message doesn’t help me to spot the problem. Is it possible to make this errors more informative?

BTW, I am talking about errors that are raised only on WebGL and not in Editor. Otherwise my post has no point.
