When encounting an empty geometry, potential bug in the ST_3DIntersects function

[Wenjing]

Consider this query:

SELECT
ST_3DIntersects(a1, a2)
FROM ST_GeomFromText('GEOMETRYCOLLECTION Z (POINT Z EMPTY, POINT Z (0 0 0))') As a1
, ST_GeomFromText('POINT Z (0 0 0)') As a2;
--excepted{t}; actual{f}

POINT Z (0 0 0) is the two geometries' intersection. So the excepted result of 3DIntersects is true.

But the 3DIntersects function doesn't consider they intersect only when inserting an empty geometry before this point.

Moreover, using the 2D Intersects function in this situation, we can get the expected result that they intersect.
