dom-repeat has a built-in feature for filtering the list:

https://www.polymer-project.org/1.0/docs/devguide/templates#filtering-and-sor...

Using that is probably better for performance and should work properly with data
binding notifications. As it is, this breaks paths and prevents the
isSelectedFolder highlught from showing up for nested folders.
