IE/Edge sometimes crash when comparing documents between frames using the strict equality operator (`===` & `!==`). Funnily enough, shallow comparisons (`==` & `!=`) work without crashing. The change to shallow comparisons in `src/selector.js` was done in jquerygh-4471 but relevant changes in `src/selector/uniqueSort.js` were missed. Those changes have landed in Sizzle in jquery/sizzle#459. Fixes jquerygh-4441 Closes jquerygh-4471 Ref jquery/sizzle#459
