For example, it is incorrect to use hidden to hide panels in a tabbed dialog, because the tabbed interface is merely a kind of overflow presentation — one could equally well just show all the form controls in one big page with a scrollbar". How is this different from the "skeletal example, the attribute is used to hide the Web game's main screen until the user logs in:" <section id="game" hidden> ... </section> Just as certain content cannot be made available till one logs in, it may not be possible or logical functionality-wise to display content of subsequent tabs in a tabbed dialog because there may be dependencies. The hidden attribute may be removed programmatically when content is to be rendered just like display:none may be changed to display:block or the like. Please can you clarify why it is not suitable in a tabbed dialog?
