Problem displaying title revisions on profile activity tab

For example, on English:

Similarly on Home Improvement:

It only happens on profile pages (the diff on /posts/X/revisions looks fine), and only on some sites

There's a 200% font-size on that page we can't really explain (since the name <h1> in the upper left doesn't get that style anyway...there's something else with a higher specificity).

A fix for both the size and overlap will go out with the next build.
