            Bug ID: 178636
           Summary: Web Inspector: [PARITY] Styles Redesign: Make inline
                    widgets work with CSS functions (var(), calc(), etc.)
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: All
                OS: All
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: Web Inspector
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: nvasilyev at apple.com

Web Inspector doesn't show inline widgets (WI.InlineSwatch) for colors, gradients, cubic-bezier and spring function
if they are or have CSS function (such as calc, var, or min/max) in them.

For example, Web Inspector doesn't currently shows color picker for `color: var(--text-color)`.

None of these functions can parse CSS variables, calc() or min/max() correctly:

    WI.CubicBezier.fromString
    WI.Spring.fromString
    WI.Color.fromString
    WI.Gradient.fromString

E.g.:

    -> WI.Color.fromString("linear-gradient(#fff2db, var(--myVar))")
    <- null
