// Normally, this would create difference in behavior: if
// `getPropertyValue` returns an empty string, the value returned
// by `.css()` would be `undefined`. This is usually the case for
// disconnected elements. However, in IE even disconnected elements

// Support: Firefox 105+, Chrome <=105+
// Spec requires trimming whitespace for custom properties (gh-4926).
// Firefox only trims leading whitespace. Chrome just collapses
// both leading & trailing whitespace to a single space.
//
// Fall back to `undefined` if empty string returned.
// This collapses a missing definition with property defined
// and set to an empty string but there's no standard API
// allowing us to differentiate them without a performance penalty
// and returning `undefined` aligns with older jQuery.
//
// rtrimCSS treats U+000D CARRIAGE RETURN and U+000C FORM FEED
// as whitespace while CSS does not, but this is not a problem
// because CSS preprocessing replaces them with U+000A LINE FEED
// (which *is* CSS whitespace)
