When the browser test for diversity emoji was added in [36160], it included a workaround for Chrome not being able to compare Uint8ClampedArray objects directly, by converting them to a string. Unfortunately, Safari doesn't support the Uint8ClampedArray.toString() method correctly, so the test was incorrectly failing in Safari.
Merge of [37028] to the 4.4 branch.
Fixes#36266.
