Is it too soon for another paragraph break problem?

I feel like I ask about these all the time. Here’s the latest:

[code]Test is a room. “This is a test[do some stuff]. [paragraph break]This is the second paragraph of the test.”

To say do some stuff:
say run paragraph on;
follow the little-used do nothing rule.[/code]

This example prints:

If I remove the “run paragraph on” line, it looks like this:

Of course what I want is this:

How do I get it?

Test is a room. "This is a test[do some stuff].[line break][paragraph break]This is the second paragraph of the test."
Don’t ask me why it works.
