Hence the word “seem”. 
I just changed the title again to test another case, when the title is wrapped. This only happens in the regular view, not when it’s in the title bar. For me, the clipping does not occur on the wrapped lines, only on the first line. So that’s good.
For more general usage, though, extra line height is required for tall scripts, as the diacriticals can not only disappear, but also clash. As a more long term idea, perhaps a theme or option for tall scripts would be useful, and show an interest in reaching out to people who don’t use Roman scripts. It would take careful testing through the whole interface, though.
