Form select elements don't match styling when disabled

[stephaniehobson]

Description

When a select drop down is disabled it gains a filled blue triangle as the down arrow. This is incongruous with the carrot the select uses for other states and I would expect it to be grey.

Steps to reproduce

1. Add disabled to the select element

Expected result

Actual result

Environment

MacOS, Firefox Nightly.
