Near the new lava lakes I noticed that when glow lichen is near lava it will be set on fire but never burn down

How to reproduce:
1- Place a glow lichen near lava 
2-Set a high randomTickSpeed
3- Observe it getting set on fire but never burning down.

You can naturally observe this happening on the seed : -8508883206669806165 (lush caves singlebiome)
/execute in minecraft:overworld run tp @s 3.75 -54.71 238.58 -813.70 37.76

I would expect glow lichen to either not be set on fire as it cannot burn, or be able to burn down if it can be set on fire.
