Wiki Tabs Wrap to a New Line
When there are a lot of tabs on a wiki page vs a small amount of horizontal space (usually fluid or responsive sites, but some narrow fixed widths), the tabs at the top can be wider than the wiki page container itself. When this occurs, the tabs wrap to the next line, and this looks weird to say the least.
This can be fixed by using Javascript to catch when there are too many tabs and start packing the extra ones into a new sub-menu.
