Courses are invisible while dragging from toolbox #81
Description
Currently, in the main-preview branch, there is an issue in which course blocks become invisible when dragging them from the toolbox to a semester block. I am still able to insert courses into semester blocks as long as my cursor releases within one.
This is not an issue when dragging courses between semester blocks or from semester blocks to anywhere else.
I don't have a video to demonstrate this behavior right now but trust me bro.
