Break/continue block does not react to movements of the parent block

[BeksOmega]

Describe the bug

When you move the parent of a break/continue block, the block does not check if it is now inside/outside of a loop:

Note: This repros on master.

To Reproduce

Steps to reproduce the behavior:

1. Add the break block, a loop block, and another block with a statement connection (eg controls_if) to your workspace.
2. Nest all of them together, with the loop block as the outer block.
3. Move the statement connection block inside and outside of the loop.
4. Observe how the break/continue block does not update.

Expected behavior

The break/continue block should update whenever it moves inside/outside of a loop.

[EDIT: The same thing does not apply to the if-return block:]

Thanks for reporting!
It looks like the problem is with this check. Since the parent block is the one getting dragged this part is failing.
