Why doesn't sketch text copy with a line?

To recreate:

1. create sketch

2. draw centerline

3. add text to the line.

4. select line and text.

5. hit copy entities on the sketch toolbar, pick a random from to

6. notice that the line copies, but the text does not.  In fact, the text is copied, but left in the original location and is not associated with the new line.

What gives?

Thanks in advance for any help!
