Wrong Python behavior after interrupting %%groovy magic

If we interrupt one cell the next cell will display result from last cell

If we try to interrupt infinite loop the cell will hangs

Start by reproducing the %%groovy magic behavior described: interrupt a cell and then run the next cell, or interrupt an infinite loop. The issue names no source file, test, or entry point, so trace the Groovy magic's interrupt and cell-execution handling first; done means the next cell no longer shows the previous result and interruption does not leave the cell hanging.
