[new_builder] Dragtool error when dragging downwards

Summary:
I am designing a windmill and the lowest wing is atached at the top and then hang downwards. I figured with the new dragtool, this would be so much easier than in the old builder, where you had to manouvre the camera quite a bit to place the blocks.
Unfortunately it did not work and this error popped up…
Steps to reproduce:

  1. Look above.
