Unfortunately there’s no straight forward solution I’m aware of at the moment for this. What you have to do is set the values on the hover object to change when read only would be true.
Edit:
Just figured out what the issue here was, first the state you want to override all states should be last the heirachy is bottom to top, bottom overriding everything above it.
Once you have sorted your state hierarchy you change the relevant style elements on the overrider state. If you’ve just created a Top state from the default settings they essentially don’t get registered, and you need to reapply those same colours. This is from something at least I just experienced trying to figure out this issue.
