21152	Kill use of colons in class names	markjaquith	azaozz	"Some of the WordPress admin uses class names with colon-separated values that have special meanings in our JS code This is a bad idea. Colons are a special character in CSS selector engines.

See #21106 for a really odd bug that cropped up because a css class contained the text {{{foo:event}}} which got parsed as an {{{:even}}} pseudo-class in JS.

HTML5 data attributes are the better way forward, in terms of attaching data to dom elements. We should kill all instances of colons in favor of data attributes."	defect (bug)	closed	normal	3.5	Administration	3.4	normal	fixed	has-patch	azizur jack@… aesqe@…
