Blocks & Decoration Meteorite and Hellstone ore/bricks should inflict "On Fire!" de-buff to vulnerable enemies

[Mr. Mastodon Farm]

I was just mining some meteorite and thought it was odd that the zombie walking on it didn't burn.

I understand it could be imbalanced giving a trap block with easily accessible immunity to the player early, but by that time the player likely has the capability to gather lava as well, so it's not so much different from that.
