ct_run & spec file with groups runs all tests

[fregate]

Describe
I have some application, tests and spec file to run different tests for different profiles (in rebar3). And if I have more than one suite I cannot run only one specified group of tests in all test suites. In spec file I described group {groups, 'This', [platform_SUITE, unit_SUITE], unit_tests}. which I want to run in tests. So If I specify only one (any) suite - it runs only tests in unit_tests group, but if I specify all or group of suites - it run all tests in its.

CWD set to: "/.../myapp/_build/x/ct_run.ct@hpw.2025-01-21_16.48.30"

Testing apps.myapp.platform_SUITE: Starting test, 3 test cases

Has to be only 1 test (1 test in unit_tests group)

and for unit_SUITE

Testing apps.myapp.unit_SUITE: Starting test, 2 test cases

To Reproduce
Run ct_run -spec spec/unit.ct.spec in app dir.
