-// We have an implicit delay on stop-hover-open before a submenu
-// closes.  This cannot be zero since it's nice to move the mouse in a
-// direct line from "current position" to "position of item in
-// submenu".  However, by doing so, it's possible to overlap a
-// different button on the current menu.  Example:
-//
-//  Folder1
-//  Folder2  ---> Sub1
-//  Folder3       Sub2
-//                Sub3
-//
-// If you hover over the F in Folder2 to open the sub, and then want to
-// select Sub3, a direct line movement of the mouse may cross over
-// Folder3.  Without this delay, that'll cause Sub to be closed before
-// you get there, since a "hover over" of Folder3 gets activated.
-// It's subtle but without the delay it feels broken.
-//
-// This is only really a problem with vertical menu --> vertical menu
-// movement; the bookmark bar (horizontal menu, sort of) seems fine,
-// perhaps because mouse move direction is purely vertical so there is
-// no opportunity for overlap.
