It looks like broken "Shift-Ins" paste in Notebook is have something to do
with the following code in the
IPython/frontend/html/notebook/static/js/notebook.js :

else if (event.which === key.SHIFT) {
   // ignore shift keydown
   return true;

If I'm commenting it out, shift-insert paste starts working again.

It looks like this code was introduced in the following commit 8dc3ac7 -
"prevented case-sensitive shortcuts if shift was pressed after control
