Problem in Sorter.
function dimsFromTarget return empty array, when target element not in draggable list
see
https://github.com/artf/grapesjs/blob/dev/src/utils/Sorter.js#L644(not found target)
https://github.com/artf/grapesjs/blob/dev/src/utils/Sorter.js#L648(return empty array)

And after this function call getTargetModel with target undefined and appears error
see https://github.com/artf/grapesjs/blob/dev/src/utils/Sorter.js#L449

Maybe need add check on exists target? Can you fix this error or i need to do pull request?

Can you tell me exactly how to reproduce the error because I don't see any error by dragging off the cell

First error.

1. Select cell wrapper(see on screenshot) and try drag it
2. In console will appear errors
   

For more details i attach link on two video files. When i tried to reproduce, i found another bug. Try select first component for example text and move it and after select cell and try drag it. You'll see that line of destination will be in wrong position

Yeah, it actually doesn't even make sense to continue onMove without the target, I'll take care of it, thanks for the insight

But is not fixed.
Repeat steps and you will get error Uncaught TypeError: Cannot read property 'indexEl' of undefined.
It can be to reproduce in your demo
