This variable name changed with the v2.0.0 of Pico-Router and it wasn't changed here. This was causing every page to display a `<div class="homePage page">` rather than the appropriate `editPage` or `sharePage`. It just wasn't immediately noticeable since `homePage` and `editPage` are almost identical. The problem is clearly visible on `sharePage` however.
`homebrew.jsx` was set to always render a defaultUrl of ` ` which creates a `<div class="homePage page">` by default, overwriting the expected `<div>` on for the current url.
I think this might be caused by a new bug in Chrome or something since it seems to have popped up in GMBinder as well in the last couple weeks. See #683
Anyway, the error only occurs on the Class Table and Descriptive Text Box, which are also the only ones to use `border-image-repeat: round`. I changed it to `border-image-repeat: stretch` which solves the graphical issue and doesn't affect the appearance otherwise in this particular case.
