Can this issue be closed? Is aria-current fully supported?

Aria-current is not implemented for Mac, Android or ChromeOS. I still haven't investigated if this is even possible, so there is a chance that most work that could be done is done here. However, I need a bug open to remind us of that.

Ok, thanks.

Hopefully this info is helpful for Mac implementation:
http://w3c.github.io/aria/core-aam/core-aam.html
Find aria-current on page and expand table items to see AXAPI entries for:
5.5.2 State and Property Mapping Table 
   -> aria-current (state) [ARIA 1.1]
   -> aria-current is undefined (state) [ARIA 1.1]
5.8.1 State and Property Change Events
   -> [ARIA 1.1] aria-current (state)

Better still, here are the latest links to those sections:
http://rawgit.com/w3c/aria/master/core-aam/core-aam.html#ariaCurrent
http://rawgit.com/w3c/aria/master/core-aam/core-aam.html#ariaCurrentUndefined
http://rawgit.com/w3c/aria/master/core-aam/core-aam.html#event-aria-current

Looks pretty trivial to finish the rest of the platform implementations

I'll mark this as an accessibility compat issue for Mac
