- * Forces emotion's speedy mode in antd-style.
- *
- * antd-style hardcodes `speedy: false` in both createStaticStyles and
- * createInstance, which causes emotion to create a new <style> element
- * for every CSS rule (n % 1 === 0 is always true).
- * With speedy: true, one <style> tag holds up to 65 000 rules via
- * CSSStyleSheet.insertRule(), eliminating thousands of DOM insertBefore calls.
