🔵 Describe the bug:
Newly added Action Blocks appear at the bottom of the macro.
Note that those created inside a Loop are correctly placed bellow the current Action Block.

🔵 To reproduce: (Steps to reproduce the behavior)

1. Go to 'tab 3' (on the version 3 of my macro "AA5_ROTATION")
2. Click on 'Add Action Block icon'
3. Notice that the new Action Block is added at the bottom, not bellow the current Action Block

🔵 Screenshots:

🔵 Expected behavior:
When the player adds a new Action Block, it should be placed right bellow the current Action Block.
