Lightning Striking Lightning Rods Can Still Set Fires

In the clip below you can clearly see that even though the lightning struck a lightning rod it still set fire to the blocks below. This seems unintentional since the whole purpose of the lightning rod is to stop lightning from starting fires to your base.

How to recreate:

• Get a Lightning Rod
• Place it down somewhere
• set weather to thunder or just wait for a thunderstorm
• observe when the lightning hits the rod and sometimes starts fires
