EXPECTED:

var x = foo() ' 

ACTUAL:

var x = foo()'

This will alternate between these two formats as you ctrl+k+d

This is invalid code anyways, so I'm not super inclined to prioritize it. We should investigate if we find it's affecting a more mainline scenario.

This test (TestInvalidTrailingQuote) seems to be passing and I can't repo this behavior on NTVS Alpha 1.2, with either Full Intellisense or ES6 preview Intellisense.

Please reopen if I interpreted this bug incorrectly.
