Refreshing the chapter page was landing the user back at the top, because
only ?resume=1 triggered the saved-position restore. Added isPageReload()
helper (checks performance navigation entry type === 'reload') and OR'd
it with the resume flag. Refresh now restores to the last scroll
position; drawer/list clicks still go to top as intended.
