flaws in test 't1900-array.pl' evaluating '~/samples/arrays.xls' with current master ver. 1.12.52 ?

I have the impression there are two flaws:
1.) 'manually' opening the test file and recalculating with 'F9' produces a 'FALSE' in 'Intersection!G29',
.... and subsequently also in 'Intersection!F4', 'Summary!B3' and 'Summary!B1',
2.) the automatic test run does not report this because it evaluates 'Summary!B2' and not 'Summary!B1',
can't say if intentional, assume not.
