Tests: Fix selectmenu width tests in Firefox with jQuery 3.0 & 3.1

jQuery 3.0 & 3.1 used `getBoundingClientRect()` in its `width`/`height`
calculations and that causes minor differences in fractional width computations.
Allow a tiny delta in tests to fix those tests breaking in Firefox.

Ref jquery/jquery#3561
Closes gh-2159
