Interesting that gn doesn't complain here. There are no targets in
//chrome/browser/ui/webui/bluetooth_internals. You want to expose this only to
the ui target:

//chrome/browser/ui:ui

Yes. It's strange. Maybe visibility doesn't work the way we think it does?

[scheib, 2016/09/30 04:25:37]

Does it throw an error if the lines are removed?
