I was referring to the <div> that ExtensionPoint.jsx adds (see its render function) to wrap the content being rendered from those specific extension point impls. The render functions adds those <div> elements and then the __renderAllExtensions converts them into the react leaf nodes and the specific extension point impl content gets dropped inside that div (or at least that is how I interpret it).
So if there's a way of getting rid of that wrapping div then that'd do the trick. As is, every extension point is a block displayed element.
tfennelly is this still needed?
