Do a search and get a list of results. They include a row of "shorts" that aren't related to the search. Two of them catch my eye.

Tap the first and watch it. Tap back arrow and the previous list is gone.

Facebook and Twitter do this all the time too, but even worse. With those I'll even view or interact with a post or tweet and can't find it later. YouTube at least has a history feature.

Which is why I rarely use the apps. But YouTube in a mobile browser is annoying in other ways.
