Fix the component toggler (#37309)

* Make the ComponentToggle remember what entity it gave components to

* fix the null problem by just ignoring the null problem

* Add documentation to the new datafield + removing the "= null" that is not necessary

* small fixes and cleaning the code

* whitespace my beloved

* wait, I dont need those lines, why did I add them?
