For reasons I've not been smart enough to figure out, there's a
difference in matching between 3.1 and 3.2
```ruby
RE_LENGTH_OR_PERCENTAGE =
Regexp.new('([\-]*(([0-9]*\.[0-9]+)|[0-9]+)(e[mx]+|px|[cm]+m|p[tc+]|in|\%))',
Regexp::IGNORECASE)
RE_BACKGROUND_POSITION = Regexp.new("((((#{RE_LENGTH_OR_PERCENTAGE})|left|center|right|top|bottom)[\s]*){1,2})", Regexp::IGNORECASE | Regexp::EXTENDED)
" top right".match(RE_BACKGROUND_POSITION)
```
matches "top right" on ruby 3.1, but just "top " on 3.2.

matches
top righton ruby 3.1, but justtopon 3.2.The previous regexp looked something like
/((top|right)\s*){1,2}/to match 1 or 2 positions separated by optional whitespace.This updates it to
/((top|right)\s+(top|right))|(top|right)/, which seems to give consistent matching behaviour between ruby 3.1 & 3.2Pre-Merge Checklist
