Try servers not helpful since this includes a binary file.
Unfortunately I did a --gtest_filter=BookmarkBar\* to self-test
which did not include BookmarkButton* tests :-(
Only change is "size" to "cellSize" on 2nd to last line of TEST_F(BookmarkButtonCellTest, FolderArrow)
)


UI review follow-up for m5 bookmark bar deliverables

Remove border of the (empty) bookmark item.
Add arrow icons for folders in bookmark bar folder windows (but not on the bar)
Scroll wheel events now scroll the bookmark bar folder windows (mostly
works; has a little leak-thru)

BUG=42026
TEST=see description

xib change: NSScrollView changes to a BookmarkBarFolderWindowScrollView
