Summary Browser crashes when drawing Japanese text on a canvas with some fonts

## TL;DR Repro: https://jsfiddle.net/9w2u1z7k/9/show Simply load the repro link above on an iPhone iOS 15 Safari. The browser will crash. Older versions of iOS work fine, so this is a regression in iOS 15. ## Details When drawing Japanese or Chinese text on a canvas (e.g. "こんにちは世界" or "測試") with a font chain that includes "-apple-system", the browser crashes. The problem disappears if the text is in English (e.g. "Hello World"). The problem also disappears if "-apple-system" is removed from the font family chain.

(In reply to Alexey Proskuryakov from comment #2) > Duplicate of bug 230187? I've confirmed that it does not reproduce for me on a build of macOS that contains that fix. I think it's safe to assume that it's a dupe of #230187.
