Word popup blocking content

When you click on a word the popup appears right over the content. Initially the popup doesn’t block the word, but hitting the arrow to go to the next word just blocks the entire paragraph. The word description popup needs to be visible alongside the entire paragraph so that we can refer to it in the context.

You can always expand the sidebar if you prefer and in that case you can see blue/yellow popups on the right, instead over the lesson text.
