Inspector when not editing;

* Highlight current condition in conditionSet view

* Addresses review comments.

* Condition matching highlighting tweaked

- Enable match highlighting during Editing;
- Tweaks to `is-current` styling;

* Don't reset the callback on destroy

* Combine multiple and single selection styling of objects

* Fix issue with applying styles in edit mode
