 bugs modalg_2 bug453_2: it fails not only on branch with this fix, but on master, without one too(please check it).

bugs heal bug210: incident, which leads to checkshape error in this test has not been detected before fix, although it existed, so test case was changed by adding TODO(now this test should be BAD), and pushed into Branch CR23794.
