start
Starts or resumes the active operation of this control.
This typically involves starting content playback, animations, data fetching, or making the control visually active. If the control was previously #stop() stopped, this method should resume its operation. Calling start()} on an already started control should ideally be a no-op or handle resumption gracefully.
This method might be called automatically after #initialize(Module) if #isAutoStart() is true, or explicitly by the player system.
This method is part of the RevelControl interface but is not actively used by RichTextView as it's a static display once initialized.
