Disable close on click outside

The problem:

While node editing, clicking outside the node by mistake close the popup.
If you have complex flow need to find the node again and reopen it to continue editing and especially hinders when editing a function in a function node.

Suggested solution:

Disable option “close on click outside” and allow to close popup only by the X button and ESC key.

This sounds like a reasonable request. Just not certain how easy/difficult it would be to implement…
