A bookmarked chat conversation's onebox overflows onto the side when the screen is skinny:
As you can see, other kinds of oneboxes (there's a question there) resize properly. However the white box of a conversation's onebox overflows off the right side. Similar behavior is observed in the transcript. Could this be fixed so the conversation onebox resizes like the question onebox?
If you're wondering what all the other links are from, I tested a few old onebox-related bug reports while checking for duplicates
