Summary: 

I was testing the stealth system in Bedrock and Java Edition, when I noticed that the invisible stealth is not the same in both editions.

Steps to Reproduce:

1. Launch Minecraft Bedrock Edition in Creative Gamemode

2. Become invisible with a potion

3. Spawn hostile mobs

4. Go to Survival Gamemode

5. Bump into the mobs

Observed Results: 

Unlike Java Edition, when you are invisible and approach a mob, you will notice its presence but not attack, as if it has become peaceful. In Java Edition, even invisible, when the player approaches a mob, it will automatically see and target the player

Expected Results:

The Java and Bedrock stealth should be the same

Notes:

The only hostile mob that attacks when bumped is the zombie, but unlike the Java Edition, you have to be very close, and it still doesn't target you.
