The Bug:

Corner vines can float in an unexpected way. (When there are several vines in a block space)

Steps to Reproduce:

1. Build this structure as shown in the attachment I attached. All normal oak fences have 2 pale oak fences underneath them.
2. Place vines on all the available exposed faces of bamboo planks.
3. Due to MCPE-140143, you have to wait for several vines in a block space to appear on all the available faces on the pale oak planks. You can set your random tick speed to 50 to make reproduction of this bug quicker.
4. Once the vines appear on all available exposed faces on the pale oak planks, break the bottom layer and the middle layer of both the pale oak planks and the bamboo planks. Do not break any fences.
5. Break the top layer of bamboo planks.
6. Congrats! You got some floating vines.

Tested platforms:

• iOS
• Nintendo Switch

Expected Results:

Corner vines should not float in this manner.
