The ant target links in the console don't work properly during a running build
So issue JENKINS-7041 seems to be fixed only partially.
It still occurs in the console of a running build.
It seems to be fixed only for the archived console output.

Detailed description:
If I look in the console output of a still running build, I can see ant targets twice in the outline, even if they exist only once.
Clicking each first one in the outline jumps to the second one in the outline instead of the first one in the console.
Clicking each second one jumps to the first one in the console, even if a second one exists.
This happens also if the build is finished, but the console view was opened before finishing.

If I open the console of the same build again after finishing, links work fine and the build targets that only exist once also only appear once in the outline.
