Allow for scrolling through Overlay Text blocks and Text balloons

We normally make text blocks just big enough to fit the English text. It’s almost guarantied that the vernacular translation will need more space than the English text. Fortunately that’s no problem, because in Bloom Reader the text will scroll through the text block just like it would do in any regular text box.

But… right now we can’t scroll through the text in Bloom Editor. It would be great if that was possible, so that we would be able to edit the text, or add pipes to break up the high lighting.

Thanks for considering!
