Update replaceAll function for browser support

Editor assessment

'Update replaceAll function for browser support' is fuzzy: 'browser support' gestures at compatibility without naming the failing browsers or the polyfill approach, and the fix type, while plausible, hides that this is effectively a compatibility shim. The body then restates the subject verbatim, contributing zero additional information and missing the chance to name the target browsers and the shim technique. No scope marks the utility area, and the issue reference is the only anchor. Understandable at the surface, unexplained in substance.
