Nesting issue causing user to peform a full web refresh


We have noticed that the nesting option from time to time crashes and forces the user to loose all their work and start again:
Notice the second field is offset, it wont move and the grid/dimensions become unresponsive. The only option is to do a refresh of the web page which looses all the filtering the user has already applied.

The issue occurs when the user drags and drops it sometime does the above, other times works fine.

Experienced this in Chrome & Opera(non chromium browser)

Please can thisd be looked into?
