How to overflow text on contents tab

[Rika Sukenik]

Hi everyone, 

On the sidebar's 'Open' tab, text overflows nicely to the next line, but on the Contents tab, text extends past the screen. I think I need to add the overflow property to class tc-sidebar-tabs-main or tc-tab-set. I'm using the Shiraz plugin for styles. tried making changes to the Shiraz plugin styles tiddler, but it didn't work. Any ideas? Thanks!!
