Item frames placed on the ground pop up if you place a carpet on top of it

Confirmed for 1.13.2-pre2.

This is intended behavior. Collision boxes that intersect with itemframe hitboxes cause them to fall off.

Is this a duplicate of MC-108320, or is it treated separately as it's about regular (Survival) itemframes, whereas in MC-108320 it's about invulnerable itemframes?

I could remove the part in my own bugpost where it says:
"Invulnerable item frames and paintings can be broken if:

• You put a block inside the entity"

and we make this bugpost here a separate where it's about itemframes generally?

In that case, the bugpost owner @unknown would have to test for invulnerable itemframes as well, here is an example command:

summon item_frame X Y Z {Invulnerable:1b,Facing:2b,Item:{id:"minecraft:stone",Count:1b}}

Like in my previous comment about a month ago, I'd like to ask if this is solely about Survival?
I tested placing a carpet onto the same space as an itemframe with the Fixed property, and it works with no issue at all, by Creative means.

Again, I also would like to know how this bugpost differs from MC-108320, and if I shall remove the part from that bugpost where it says "you put a block inside the entity", as this is what this bugpost here seems to be, and would usually be a duplicate of MC-108320, whereas, again, you can by now do that by Creative means, as also MC-123221 shows.

Command used:
summon item_frame X Y Z {Fixed:1b,Facing:1b,Item:{id:"minecraft:porkchop",Count:1b}}

Place a carpet onto the same block the itemframe is; you can of course also do that before you summon the item frame.
