Oh, I see it now, indeed, that option is not working correctly. That is a new issue, that nobody else noticed before.
I’ve looked up the code, and it accidentally takes the value set on the General Options -> Limits panel. If you change the limit there, it should solve the problem, without making changes to the code, or using custom code: http://i.imgur.com/PfbCUsx.png
I will make sure to fix this for the upcoming release.
I hope this helps!
