Gravity blocks don't fall when placed on replaceable blocks

Summary:
Gravity blocks don't fall when placed on replaceable blocks.
For example, if you need to put sand on the grass, for this you will need to place 2 blocks next to each other and place a block with gravity above the grass, aiming at one (upper) of the placed blocks. This is also described and fixed with the snow layer in MCPE-151407.
All blocks that can break when blocks with gravity fall on them are affected (except snow, starting from the version 1.18.30.21 Preview, 1.18.30.20 Beta).

Affected Blocks:

• grass

• tall grass

• fern

• large fern

• sea grass

• tall seagrass

• vine

• glow lichen

• warped roots

• crimson roots

• nether sprouts

• dead bush

• structure void

Steps to reproduce:

1. Place any block that can break when a gravity block falls on it or that can be replaced with another block (eg Dead Bush).

2. Place 2 blocks side by side (if you used for example Tall Grass place 3 blocks).

3. Aiming on the topmost placed block, place above the replaceable block, the block that has gravity.

Observed results:
The block did not fall.

Expected results:
The block should fall and break the block underneath it (as in the java version and as with the snow layer from version 1.18.30.21/1.18.30.20).
