We would like to build jquery ui in debian from the source repo. We already have grunt 1.0.1 in debian, but jquery-ui is using grunt 0.4.5. When we try to build jquery ui using grunt 1.0.1 , we get the following error,

$ grunt --verbose
Initializing
Command-line options: --verbose

Reading "Gruntfile.js" Gruntfile...OK

Please make it possible to build jquery-ui using grunt 1.0.1

JSFiddle: ​https://jsfiddle.net/pastorjayrich/crvh9ava/

1. Only repros in IE9-11
2. Only repros for the “arrow” key (tabbing into and out of the control always resets focus indicator). It is expected behavior for an arrow key to lose focus as it is technically reading mode.
3. Hovering over an element that is missing focus indicator resets focus indicator.
4. Works as expected in Edge, Chrome and Firefox.

Expected: Browser provided visual focus indicator should be present when navigating tas with either the tab key or arrow keys. Actual: Tabbing into and out of the "tabs" causes the VFI to appear. Also, on mouseover of an active tab, the VFI will suddenly reappear.

Calling $('selector').button() on multiple mixed elements including both input-checkbox and simple a link doesn't work anymore with 1.12.

I created a simple jsbin to reproduce the issue: ​https://jsbin.com/ticaxovima/1/edit?html,js,console,output

Maybe the compatibility layer to call "checkboxradio" widget instead of the button widget leaves garbage in the button widget.
