In T290521 logging for live and non-live previews was added. This ticket is to do the same for the three realtime preview actions that we're interested in:
- preview-realtime-on β The WikiEditor 'Preview' toolbar button was clicked to turn the preview panel on.
- preview-realtime-off β The WikiEditor 'Preview' toolbar button was clicked to turn the preview panel off.
- preview-realtime-inuse β Fired without user interaction when the WikiEditor preview feature is already on when the editing form is opened. Requires T294599 to be done first.
