Write unit tests before we look into this.

This is due to the block

			if ( haveAte && stream.sol() ) {
				// @todo error message
				state.nTemplate--;
				state.tokenize = state.stack.pop();
				return;
			}

in eatTemplatePageName()
If I remove it, things seem fine. I can't exactly tell what the purpose of this fragment is, but it has been there since the inception of the mode. @Kaartic any idea ?

I pretty much do not remember contributing to Code Mirror nor having experience with it's code. Was that a wrong ping?
