Observed Behaviour:

• While navigating in Jungle we can spot randomly floating vines around the trees. It is a rare thing to run into, but it is possible to spot vines generating just in air.
• Sometimes jungle trees are generated in half, I think this might be related to the vines generation since they generate around trees.

Expected Behaviour:

• In my opinion vines is not supposed to be floating in the air.
• Half of tree cannot be generated naturally.

More information:

• Probably the most similar issue is MC-18581, but I haven't destroyed any tree. Floating vines were generated naturally.
• MC-196205 was really similar, happening on swamp biomes.
• 2 of the pictures shows half of tree generated, might this affect floating vines on the other side sometimes?
• For trees generating in half this might be related: MC-128526.
