- media sites like YouTube (some people prefer that when they click on a new video, it actually starts playing) - notification sounds - playlists of any sort (music or video) Most of this can be worked around by prompting the user on load and then never reloading the page (SPA fetch-and-replace pattern), but even big sites screw this up (like YouTube, where the memory usage increases with every "fake reload"). Again, I wouldn't want just any site to do this unexpectedly, but the ones where I want those features should be able to do it.
