…ove screen reader accessibility Adds a visually hidden span as a child of the accordion header/button which has a generated id for the associated accordion content panel to reference if/when the accordion header/button is disabled. This should allow screen readers to have an active reference for aria-labelledby to reference. Fixes b/438312273
…ccordion trigger parent element Updates previous change to move the visually hidden span from being a child of the accordion trigger button, to being a child of the parent wrapping the accordion trigger. This prevents it from being hidden by aria-disabled or disabled attributes when being a child of the trigger.
