Are they always duplicates? I see some (Details)(Details) on som-staging right now <https://sheriff-o-matic-staging.appspot.com/chromium/examine/chromium.mac.Mac10.10%20Tests.components_unittests.> but they go to different links. From the alerts json:

suspected_cls: [
{
commit_position: 414428,
repo_name: "chromium",
revision: "52f7671273011c930c4f1ba8a252eac426f88948"
},
{
commit_position: 414443,
repo_name: "chromium",
revision: "330958ddcdcd0084d724571eddaa66f9c364115f"
}
],

The styling on multiple links is pretty bad, which probably makes it hard to tell that they are all different.

Findit might be returning duplicate results, though.

They're not always duplicates but there were cases I saw this morning where there were many duplicates. 

I'll take this and also change the details link to be the short git hash or something.
