Mozilla Bug 780258

All of this text should be completely contained within the blue box.

Don't let tomorrow find you wishin'. Boy, you've got a mission. Shake it, rattle, and roll. Now, just use your intuition. You'll get less competition from the clock up on the wall.

You are what you are. You dream what you dream. Play on your blue guitar for me.

This text should not apply the max line box width, since it exists within a constrained height block. This is used for limiting the reflow-on-zoom feature for constrained height blocks, since otherwise they could overflow into an element later in the document, or potentially have their text cut off vertically.
