<p>I once knew a man, showed me the sleight of hand.
|
|
In the blink of an eye he danced across the strings.
|
|
He played a song I've never heard; poignant and absurd;
|
|
To this day, it leaves me wondering.
|
|
<p>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.
|
|
<p>You are what you are.
|
|
You dream what you dream.
|
|
Play on your blue guitar for me.

<p>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.
