In my opinion, text or dimensions should have a new property called "full style match" in the Properties window. This property would be below the "style" property.
This property would be just ReadOnly and it would be a boolean property (Yes/No).
For example, if we add a text according the active text style, then this property will be "Yes", but if the user changes some value properties so that the text does not strictly adhere to its assigned style, this property will be "No". (there is no fully match with the assigned style).
For the case of "Element Template" property, it would be also necessary a similar property : "full Element Template match" (Yes/No).
Regards.
