React [pools events](https://github.com/facebook/react/issues/2850),
which means that once the lambda runs later on the properties we want
to read will be null. Instead, we capture the properties in the event
loop.
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.
When adding the Class Feature snippet, all curent text in the document is inserted in place of the randomly generated class name, creating several duplicates of the document and generally creating a mess. See #413 which was closed but the issue was never fixed.
Most of the snippet code generators do not have any input arguments in the `module.exports` function, so they don't have this issue. However, Table of Contents needs to parse the text in the brew, so it is passed a copy of the brew document. Unfortunately, Class Feature (classfeature.gen.js) also has an input parameter for when it is used as part of the Full Class snippet. Thus, the unintended consequence occurs in snippetbar.jsx in the `execute` function.
This fix simply adds a check to the execute function and only passes in the brew as an argument if the clicked snipped actually is the Table of Contents. Some restructuring might later reveal a cleaner way to do this rather than an awkward special case check like this.
Previously, this relied on a hard-coded constant determining the
height of a page. However, that's unnecessary -- we know the scroll
height of the window and the number of pages, so we can compute it.
