Delphis FormDesigner don't know what has changed and still works. All values
are read just in time via RTTI.
There is a reason for this:
If a property is changed, some other properties can change too. How will the
TComponentInterface ever know, if not by reading all from the RTTI?
What value changes the FormEditor needs to know?

It "stores" the values simply via the RTTI. For integer values this is a
simple SetOrdValue. In fact, it changes the real value of the running form.
