Wrong icon in application selector

[eh-am]

edge is grouped correctly, but the icon is wrong (it should be a folder).

To reproduce, mock the /label-values?label=__name__ response to

[
  "edge",
  "edge.alloc_objects",
  "edge.alloc_space",
  "edge.block_count",
  "edge.block_duration",
  "edge.cpu",
  "edge.goroutines",
  "edge.inuse_objects",
  "edge.inuse_space",
  "edge.mutex_count",
  "edge.mutex_duration",
]

Not sure, but I this happens because of something like "edge.edge"
