Some of the bugs got fixed, some of the tests were wrong and got deleted, and the rest of the tests got moved to a to-do list.
It is important that people be able to run the tests to see if they broke anything. This cannot happen if tests that are known to fail are mixed with tests that are supposed to succeed.
Perhaps you have never worked on a project in which all tests worked all the time. This is an important tool in achieving high quality software.
