Placing fallling blocks using /setblock can cause a client-side lag spike in some circumstances

Using /setblock to place a falling block in air will cause a game freeze in some circumstances.

One of these can be found in the attached world: placing a block at y<32 won't cause a freeze, on the other cases it will.

That's not the only case, i didn't find why this is happening despite different tests.

I have recorded a video showing the performance issue while executing a metric capture. Both of them can be found in the attachments.

Seems MC-261857 was actually a duplicate of this, but because this was reported specifically for falling blocks (rather than any), it wasn't found. So this was caused by MC-170010.
