Fix CJK fonts again and misc. font issues (#14575)
* Push system-ui further down the stack, fix #12966 * Fix Firefox showing U+300x in emoji font and more * Revert emoji font and fix long-standing Safari bug * Exclude Safari emoji fix above 1.25x zoom * Minor correctness/typo fix, affects only legacy platforms * Emoji consistency for monospace (e.g. EasyMDE) * Override paradigm; macOS/iOS-specific metric fix * Move whitespace fix to font-face * Handle metric calculation errors with Firefox * One last workaround for aliased fonts in Linux
