The bookmark manager, which shares these icons, is weird too -- it displays a closed folder until the tree item is expanded, at which point it's open (i.e. the way comment 0 says we "should not make this work"), but if you then delete the contents of the higher-level folder, so it auto-closes, the icon gets stuck "open".

Windows native behavior would be to use a single closed folder icon for all these states.  Is there any formal Chrome design policy regarding this, or can we safely just do what it sounds like Win and Mac both want and remove the "open folder" state entirely?

+CC bettes for that.

M-56 clearly didn't happen.  Dropping priority; we can ship phase 1 without fixing this.  That said, it seems like we can just use a closed icon all the time and simplify the code.

->bettes to veto that if necessary.  If he says OK, this goes into the "nice to have" pool and gets marked Available.

(It sounds like https://codereview.chromium.org/2772613003 may have fixed this on Mac, optimistically unmarking there)

The expected output in c1 SGTM. Thanks!
