div.CodeMirror-selected for bespin

[stdedos]

Hello there,

I'd like to propose a change for the div.CodeMirror-selected selector for bespin

Line:

codemirror5/theme/bespin.css

Line 12 in 34b8435

.cm-s-bespin div.CodeMirror-selected {background: #36312e !important;}

should become:

background: #595959 !important;

or equivalent.

My proposal is an educated guess by looking around the repo, "what looks best", "sticking close to the theme colors", and by the intuition that "there won't be any setting that would get AA(A) a11y score"

Discussion here: openstyles/stylus#1538
