Wayfar 1444 maps do not display properly on mudportal

I'm not exactly sure if this was working fine before, but I believe it was. When playing Wayfar through mud portal, the display looks like this:



However on putty and mushclient, the maps properly display like so:



I'd really like to use mudportal for the "play now" link on my website, as the client I currently use is flash based, which is becoming depreciated. Could there be something on my end causing this?

It looks like a wrapping issue, although on mushclient with an 80 line length everything shows up correctly. Any advice would be appreciated, or some way to specify longer line length per game (since there's a lot more real estate on the html5 client anyway).
