This report doesn't come as a surprise. I reported
Bugzilla Bug 167315
[FIX] TITLE string should be "sandboxed" in September 2002, though the focus was then on not passing an infinite string to the window manager and crashing that. Title string bounding is pretty obvious, really.

I opened a bug on this exact behaviour a while back. Pile in.
