One thing that confuses me is that I had the same tube installed previously and it didn't seem to be drawing grid leakage current. Voltage on grids of both 27s were stable and close the the voltage of the battery itself.

What would cause a tube to develop this condition? Is it related to circuit design or operating points?

Is there anything that can be done to reduce or eliminate the problem, other than just using a different tube? Or is it even a problem?

Will adding a grid stopper help?
