"Reset" on property values doesn't work as expected

Issue type

UX/Interaction bug (incorrect behaviour)

Bug description

If you've modified any property value for any element there's usually an option "Reset" (sometimes just an icon with an anti-clockwise circular arrow) that presumably means "I don't want this property to use a special value any more, it just should use the style default". But unfortunately that's not actually how it's implemented - it's implemented as "Change the value to whatever the specific style default value is currently", meaning that if you then change that style default value later, any property values you've changed then used "Reset" on do NOT update, despite the fact that other property values that have never been changed from the default DO update when the default is changed.

Steps to reproduce

1. Create a new score
2. Add 3 text elements
3. For one of them, change a property value (e.g. frame type). Then click "reset" and confirm it changes back to the score default (usually no frame).
4. Now edit another one of them, change the frame type to rectangular frame, then choose the option "save as default style for this score"
5. Note that of the 3, two now show "rectangular" frame, but the one modified in step 3 does NOT.

Same behaviour if it's some style value you can change from the Format|Style dialog.

The problem is purely that "reset to default" isn't implemented as "delete the specific value set for this property, so that this property always takes the default value", rather as "change the specific value to whatever specific value is currently set as the default value".
