Invalid CSS with 'border-right-color: none'

[bananastalktome]

I came across several instances where we had 'border-right-color: none' in the stylesheets. Because 'none' is not a valid color value, the style appears to be ignored. I am not sure what (or if?) to change these to, but they appear as follows:

./wp-admin/css/colors-classic.dev.css:2356:
./wp-admin/css/colors-classic.dev.css:2390:
./wp-admin/css/colors-classic.dev.css:2421:
./wp-admin/css/colors-fresh.dev.css:1962:
./wp-admin/css/colors-fresh.dev.css:1996:
./wp-admin/css/colors-fresh.dev.css:2027:

Another oddball border issue: ./wp-includes/css/editor.dev.css:1992 sets property border-bottom-right-left (should this be border-bottom-left-radius maybe?)

Let's make a note to discuss this and #20586 (and invalid CSS in general) today in #wordpress-ui.

The value you'd want instead of none is transparent.

The border-right-color: none lines were merged in from the formerly-separate rtl CSS files (see r18579). They only apply for rtl.

20587.diff fixes the border-color: none instances mentioned.

20587.2.diff​ fixes comment:1.

Per line 1797, it should be border-bottom-left-radius:

20587.2.diff is a no-brainer. :-) Looks good.
