When inserting blocks into the editor, it inserts it as a <div> which means you can't use a block inline. For example, we have tried to replicate Dynamic data functionality using a block, but we're unable to use the block in the middle of a sentence. It splits the sentence into 2 <p> tags with the block <div> in the middle. 

Currently as a workaround we are changing the <div> into a <span> but there are drawbacks to this method - not having the "Go To Block" function, and it doesn't register as being used when trying to delete the block.

It would be good if blocks in the editor weren't tied to being in a <div> so that they could be used inline.
