Sketch changed when mirrored

I've versioned a documet that I'm having a problem with: https://cad.onshape.com/documents/d00ceaba15e3ae5795e20cc8/v/e1306259ed2b791bba55a81d/e/5b289bdfe74c787a08ec07e3

There's a sketch "Sketch 2", on a plane parallel to the "Front plane"
The angle between two lines of this sketch is as follows:


Then I've mirrored this sketch by the parallel mirror plane "Front"
And on the mirrored entity the angle between those lines is different:


How could it happen?

I've checked that all the vertical and horizontal lines on both sketches are parallel, but not the inclined lines.

    @MBartlett21 that may well be the root cause, but in this situation, I don’t think that would have an effect. 

    EDIT: I take that back. Deleting the external constraint in the lower left corner fixes the mirror. The link you shared refers to a feature pattern limitation, whereas this presents itself as more of a bug, but it's the same thing. I will add this as a test case for fixing.
