Locked widgets are still moveable by other widgets #1181

Subject of the issue

When setting widgets into a locked mode and adding new widgets above it the widgets are been pushed down including the locked widgets.

Your environment

• Chrome 80.0.3987.122

Steps to reproduce

I've added a locked widget. Adding new widgets above it will eventually push the locked widget down.

Expected behaviour

A locked widget should never move under no circumstances. It should hold it's position and new widgets the collide with it should be put below it

Actual behaviour

New widgets push the locked widget down.
