AvalonEdit issues with file has a very long line. #376

I have used AvalonEdit in my project. The highlighting system has a problem loading a file with a very long line. The editor will be stuck when I enter a new line (see the attached image). This problem could reproduce by using the 00 MVVMDemo project to load this file. Does anyone have any ideas as to what could help speed it up?
