Subject: [PATCH 10/34] Selecting parents: Try clickthrough.

Clickthrough has you select the parent before you can select the child. This is already in place on the mobile breakpoints, this just expands it to desktop as well.

It is a work in progress, right now it is not working as intended: once you have "unlocked" the deepest level, it becomes immediately locked and you have to click through the layers again to unlock it again. The deepest layer should always be unlocked until you deselect all blocks again.
