Title: Update media/src/core/core.sort.js

Change so that aria-label and sort area always set in each block to eliminate the need to call removeAttribute.

Should be quite a bit faster, but work out to be the same code size.

jsperf for remove & set vs. just setting:

Also simplify length comparison (> 0 isn't really needed)
