>  The CSS Color Module Level 3 specification defines the [opacity](https://drafts.csswg.org/css-color-3/#opacity) property as taking <number> values. Meanwhile, the CSS Values and Units Module Level 3 specification [discusses the precision of numeric data types](https://drafts.csswg.org/css-values-3/#numeric-types) like so:
>  
>  > CSS theoretically supports infinite precision and infinite ranges for all value types; however in reality implementations have finite capacity. UAs should support reasonably useful ranges and precisions.
>  
>  This test fails in WebKit because it requires the provided value to be round-tripped through the computed style even though they cannot all be represented as precisely as the test entails. We update the test to compare values with a small alpha.
