Call Block Glitch

So I was doing the One Block Challenge, when I encountered these glitched blocks:
Snap! One Block script pic (1)
Snap! One Block script pic (2)

How to reproduce the glitch:
Run this block:
Snap! One Block script pic (3)

The sprite should now be saying the call block.

Drag the ring out (the ring should have duplicated, and without placing it down in between, drag the ring into the ring. Now drag the glitched block and place in on the stage, and drag the first ring out again.

If it needs clarification, just ask

This glitch will also work with any other blocks with the ring thingy (idk what it is called)

I also was able to get this block:
Snap! One Block script pic (5)

just saying, a really similar issue was reported recently, and will be/is fixed in the dev version.

Oh okay. Do you have the link to the topic?

This is already fixed, isn't it? The method of setting it up may be different, but the actual outcome shouldn't be possible any more

The fix (apparently) only applies to the palette, not the stage where the blocks are coming from. However, I wouldn't be sure to expect this to be fixed, because the way the call block is ending up in the speech bubble is likely an unintended behaviour.
