For example, the removed "x" value on second display is read again:
Here:

Seems that getIntValue doesn't care if a node was deleted or not. It
simply reads it out, and gets a default value: that is 0. That's why
x = y = width= height = 0 and the dialog sits in the corner and is
"transparent" (it isnt' transparent -- it just has no size).
