SourcesTree: (index) click weirdness

[darkwing]

The first time I click on "(index)" in the SourcesTree, the following item is focused:

// console.log'ing from inside `focusItem()`
Object { name: "(index)", path: "https://davidwalsh.name/", contents: {…} }
Object { name: "(index)", path: "https://davidwalsh.name/", contents: {…} }
Object { name: "root", path: "", contents: […] }

If I click it again, I get:

Object { name: "(index)", path: "https://davidwalsh.name/", contents: {…} }
Object { name: "(index)", path: "https://davidwalsh.name/", contents: {…} }

The Object { name: "root", path: "", contents: […] } item appears to be what throws the highlight off. We need to figure out where that's coming from to fix this bug.

The problematic Object { name: "root", path: "", contents: […] } item is coming from ManagedTree:

highlightItem(highlightItems: Array<Item>) {
  // ....

  //... the last line:
  this.focusItem(highlightItems[index]);
}

The index in question is 0. Changing the code to the following appears to fix the issue:

if(index === 0) {
    return;
}

this.focusItem(highlightItems[index]);
