Code coverage in sapui5 OPA5 tests

i can see that in SAPUI5 Qunit tests there is option for checkbox for check the code coverage (by checkbox or with an URL parameter ?coverage) But in OPA5 tests in sapui5 there isn't checkbox for code coverage and if i add the URL parameter ?coverage, the test run regular without code coverage. OPA5 test in sapui5 doesn't support code coverage?

Thanks!
