I suspect PR #1547 will end up superseding this so I've highlighted this PR there to ensure changes address this concern.

correct @castastrophe .
my latest push to #1547 0483da1#diff-d430d658923968f4c3594512a47549baec7603fff5a59ad37a154be96d72584cR403 should fix this.

Maybe we could close this PR.
