Operator <<->> incorrectly calculates m distance

[dbaston]

When computing the m-distance between points and lines, the m ordinate of the first geometry is ignored.

SELECT 'POINT M (0 0 100000)'::geometry <<->> 'LINESTRING M (0 0 5, 0 1 6)'::geometry AS dist;
 dist 
------
    5


SELECT 'POINT M (0 0 1e9)'::geometry <<->> 'LINESTRING M (0 0 5, 0 1 6)'::geometry AS dist;
 dist 
------
    5
