A use-after-free vulnerability can occur while re-computing layout for a
“marquee” element during window resizing where the updated style object is
freed while still in use. This results in a potentially exploitable crash.
This vulnerability affects Thunderbird < 52.3, Firefox ESR < 52.3, and
Firefox < 55.
