Created an attachment (id=291153)
Somewhat of a runtime check
This adds a system metric, it does a test-the-waters icon rendering and if nobody's home then it will cause the check to fail and thus not attach the system metric. I haven't made anything to use it yet so this patch by itself won't fix the bug but it brings us very close to CSS-only fallbacks.
