TransformPositionArea() incorrectly assumed two-value input

Crashed when input was not a pair, but assumed it would be.

For logical values like position-area:start, we can store the value as
a single keyword, but the flip-block version of it needs to be two
separate values.

position-area might be represented as a single keyword depending on
which it is, but it's irrelevant whether the non-flipped value was a
single keyword or two keywords. For simplicity keep identical values.
