teoz: activation breaks parallell lines

Question

Hello!

Strangely, when using activation, it interferes with teoz rendering, so that messages using &, despite that do not render on same row.

Example: 

This example in code:

Rendered:

If you comment out activation, (lines 8 & 9 and ++-- on line 12) it is rendered as expected.

Thanks for a great tool!
