Assign to pschaffner@: Please provide the icon.

For the history menu cells, use the same cell metrics as those used in the tools and tab switcher menus (see here: https://bugs.chromium.org/p/chromium/issues/detail?id=817795#c5), with these exceptions: 

- menu item text color: black
- cell height: 44pt; trailing-edge truncation with ellipsis; single-line
- cell icon background rect: 28x28pt; black @ 3%; 7pt corner radius;
- cell icon favicon: 16x16pt favicon centered vertically+horizontally on top of the background rect; 2pt corner radius; clips to bounds; transparent background

NOTE: I'm waiting on confirmation from the design team for the correct favicon fallback glyph to use. You can use our current in the meantime.
