When a blaze is damaged, other blazes nearby still rise up and track the player through blocks.  They now simply do not shoot as in previous patches.

Please see the screenshot - this is having punched a blaze (with only feet showing) - all blaze around now fly upwards and track the player's movements - but do not pull aggro (no fire charges shot).

More screenshots added showing the effect when the player hits a blaze.  The player is completely enclosed in blocks and yet the blaze have surrounded the player and are tracking.
