Paintings and Minecarts and Boats can be broken by players with custom defaults permission level.

I don't know if this is the original specification.

Steps to reproduce:

1. Create any world in creative mode
2. Place a painting on a wall, and a minecart on a rail , and a boat on the ground
3. Change to survival mode and set your permission level to "custom defaults", which equates to having no permissions at all
4. Punch the painting and minecart and boat, you'll be able to break both
5. Place the minecart and boat, you'll be able to place both  

Observed Result:
You can break paintings or minecarts or boats even when they shouldn't be able to as Custom defaults permission level also You can place Minecarts and boats

Expected Result:
You cannot break paintings or minecarts or boats
You cannot place minecarts and boats
You shouldn't be able to do anything but get in and out.

Notes:

• I use machine translation because I am not good at English.
• I was used as reference similar to MCPE-132869 in visitor mode, which is a resolved issue
• Are there any differences between visitor permission level and custom defaults permission level specifications?
• Custom defaults permission level can interact the bed but visitor permission level cannot interact the bed
• Visitors cannot sleep in beds or set up a respawn point MCPE-154518
• Has the specification changed by modifying MCPE-132869 ?
