Safari doesn't work if a tag's ID is all numeric.  The current HTML spec states:  "IDs can consist of just digits, start with a digit, start with an underscore, consist of just punctuation, etc."

HTML specification is not applicable to CSS selectors. Per the CSS specification: an all-numeric id should be escaped, see https://www.w3.org/International/questions/qa-escapes#css_identifiers

However, if you change the CSS selector to #\222 it still doesn't work.

I now see that \2 is not a "2"...  It should be #\32 22 as you can see in the examples of CSS escaping linked above.
