Style regexes for shorthand properties are too strict about the order of values

The style regexes used for validating the values of shorthand properties seem to require values to be in a specific order when the CSS2 specifications allow them to be in any order.

For example, the border-top specification says that the value must take the form [ <border-width> || <border-style> || <'border-top-color'> ] where "A double bar (||) separates two or more options: one or more of them must occur, in any order."[1]

However, wysiwyg_filter will not accept the value unless it is in that exact order <border-width> <border-style> <border-top-color>.

This is causing valid styles to be removed. For example, I had a user trying to paste a table from a word document into ckeditor.module and the cells had a style="border-bottom:solid #A6A6A6 1.0pt" attribute which was getting deleted due to the border-width being placed at the end.
