            Bug ID: 166928
           Summary: Web Inspector: cubic-bezier editor behaves poorly for
                    invalid inputs in component fields
    Classification: Unclassified
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: All
                OS: All
            Status: NEW
          Severity: Normal

Entering anything that's not a non-negative number turns the text field value into NaN and puts NaN into the property declaration in the sidebar.

In this case, I would expect it to not edit the property declaration in the rule. It should highlight the bad value in red and explain why it's invalid (perhaps with a popover when hovered/selected), allowing the user to fix it themselves or click a button to revert.
