GUI - fix scope style switching on RP

* Scope now switches style without requiring a resize
* This is because we now refresh all internal scopes on a standard refresh regardless of whether there is data to render or not
* Scopes are auto-paused with inactivity anyway, so this isn’t an efficiency loss
