hasFocus binding not working

[derrickb]

Hello, there seems to be a couple old issues posted about related problems but there isn't a solid solution, or the jsfiddles no longer work:
#106
#96

Here's an updated, simple jsfiddle demonstrating click-to-edit not working as expected:
https://jsfiddle.net/derrickb/v6jwafy7/

Click on one of the click-to-edit texts, then try clicking on the sibling text lines. The input does not lose focus.

The only solution I've found is extremely hacky: I add a click binding to almost all elements that make sure that the previous element loses focus. It would be great to have hasFocus working as intended in knockout-sortable, the way it does in regular knockout.
