Value isn’t properly read when the value is keyed with a dot in the iteratee

How often can you reproduce it?

• Rarely
• Unable
• I didn’t try

Description:
If the value being iterated over has a dot in it's key, can-stache does not render that value. I added the question label, as replacing the for-of with just the for helper and using scope.key (as per @justinbmeyer suggestion) works just fine.
It might be a bug, or it might just be bad syntax/usage of the for-of helper.

See the codepen below for an example of both uses, and the results.

Steps to reproduce:

Expected results:
I would expect the for-of helper to handle/escape the dot in the key and still render. @bmomberger-bitovi had suggested this fix in the Bitovi Community

It should escape dots in `key`, so:  `var value = new KeyObservable(object, key.replace(/\./g, "\\.");` (edited)

Actual results:
it doth not render, alas
