If I'm not mistaken, it looks like you're committing our actual bugs.json database to the repository.

Does the leaf.svg have to be 83,955 lines to load the image properly? If so, we may not be able to use an SVG for this image. It looks like you're also committing a leaf.png file; if this is the same image, can we just use that? Either way, I believe this file is supposed to be passed to the Ghostery Extension from the Account project, so should it be removed from this PR altogether?

Lastly, the RadioButtonGroup.jsx file in this PR has been edited quite a bit in your #510 PR after some requested changes there, and I just want to make sure that you're planning on merging those changes into this branch before merging this one.
