Select.hideCurrent now removes the outgoing tab from the DOM and disposes its component (firing exitDocument and disposeInternal), instead of just calling .hide() and leaving an inactive but live component in the document. This fixes unbounded DOM growth in long-running SPA sessions where users browse hundreds of routes and every previously-visited tab stays cached in the parent's content element with display:none.
