I believe there is an issue where the styles I created for a breakpoint (i.e., the instances, such as a / h1, etc.) for the rich-text block are not displayed on the other breakpoints in the panel. This means that I cannot quickly check how large the Rich-Text H1 is set on mobile, as the instance is not displayed.
It would be very helpful if the instances that were manually chosen would automatically remain for the other breakpoints, allowing for quick access and adjustments where necessary. This would significantly improve the design for various breakpoints.
