[issue39827] setting a locale that uses comma as decimal separator breaks tkinter.DoubleVar

See also issue12558 which exposes the other side of the same issue.

Las time I looked at it, it was inherently a Tcl issue. In some places it uses locale-dependent formatting of floating point numbers, but locale-unaware parsing, or vice versa.
