Flickering Fire at Crimson Roots & Nether Plants

Place crimson roots (or weeping vines, nether sprouts, warped roots) near lava (which is common in the nether by generation) and they catch fire, but don't burn, the fire goes out (nylium) and reappears.
Set randomTickSpeed to something high for faster testing.

The plants obviously shouldn't catch fire and they already don't catch fire from fire blocks.
