It turns out we are creating a data-uri SVG for the delete button, but are using string interpolation for the color. If you use hex, this breaks the image on Chrome (but not Safari). Using a standard css color keyword (alternatively using RGB) fix the issue.
The reason this was made configurable AND changed is that dark
backgrounds may be able to use a smaller stack glow, but we want the
default to be more obvious than it currently is.
