Blacklisted test fail on MacOS occasionally, and when failing it will print out coordinates like this:
This will cause the whole test to became a failure in the end:
If the blacklisted test is passing then tests are PASSED. So, the blacklisting does not help here. I don't know if the problem is in build machine configuration or test itself but it causes flakiness in the system.
And also, I think this will affect all Qt versions having MacOS 10.13 as a target.
