Armor stands delete weak blocks like tallgrass

When you place an armor stand on weak blocks like tallgrass, double tallgrass, seagrass, and almost every other block that usually gets replaced if a block gets placed on it, the armor stand replaces it behaving like a block. In the attachments, there is a video that shows what is wrong and another one that shows how armor stands should normally behave.

Steps to Reproduce:

1. Place tall grass
2. Place an armor stand on the tall grass

Observed Results:
The armor stand replaces the tall grass.

Expected Results:
The armor stand should not replace the tall grass.
