The empty area to the right of a block control toolbar should be clickable

Right now if you click the area above a block, no matter how few items there are in a toolbar, the entire area soaks up the click. Ideally only the actual buttons in the toolbar should intercept clicks.

As we fix this we need to be mindful of blocks that do not have a toolbar, as the actual toolbar element still needs to have a height in order to compensate for the positioning that's done using negative margins.
