Is this a bug?

I don't think so. The point of the Dynamics context is to align the dynamics put into it on a common baseline. If there were another ^\markup ... at the point of that note with a ledger line, the alignment would force the first markup to much higher (just add s1 s1^"text" in MI to see it). There is a tradeoff between making the line of dynamics look like it's consistently above the staff and not pushing it farther than necessary from the staff. I think LilyPond's behavior here is legitimate, though perhaps the text script should go higher than it does (with the ledgered note).
