When drawing text onto a Canvas via context.fillText, Safari on iOS 15 is crashing if that text is Japanese and you use `-apple-system` in your font list. If you remove `-apple-system` or the Japanese characters, the crash stops.

Notes
* I can reproduce this in both the simulator with iOS 15.0 and physical iPad with iPadOS 15.0
* We cannot reproduce this on iOS 14 and below
* I also saw the crash when using `system-ui` in the font list
