Floating dripstone tips are sometimes left behind from large dripstone pillars

When a long dripstone pillar is broken at its top, it doesn't fall(MC-206578). Because of that bug, you can break many of the middle dripstones beneath the top block without the entire pillar falling.

This leaves behind floating tips which cannot have pointed dripstone placed beneath it(they just fall off). I believe if placed above the floating tip, both the tip and and the new block fall.
