Web Inspector: warning icon for unrecognized style rule should have tooltip

[Joseph Pecoraro]

When a CSS style rule is "not parsed okay" it has a warning icon. However, the reason
that warning icon is there is not known. There should be a tooltip, or something else,
with the image to explain to user why the warning is there. There could be a number
of reasons:

  - unknown property (-moz-something: ...)
  - unknown value for property (color: a)
  - other?

Currently the image is inserted via CSS if the property was (!parsedOk). The
CSS in inspector.css is:

>  .styles-section .properties li.not-parsed-ok::before {
>      content: url(Images/warningIcon.png);
>      ...
>  }

[Joseph Pecoraro]

Another issue might just a syntax issue. That is probably indistinguishable between an
unknown value for property.
