I tested this in 1.15.1 on Linux.
The bug doesn't affect pillagers or zombies.
The affected blocks are: honey blocks, slabs, soul sand, trap doors.
The unaffected blocks that I tested are: slime blocks, stairs, fences, carpet, fences with carpet.

Confirmed in 1.15.1, slime blocks are also affected. Video
