Why doesn't support 'display:-webkit-box' ?

[TooBug]

I'm using grunt-contrib-csslint, but not sure whether this problem comes from the original csslint, so write it here.

when using display:-webkit-box, there exists an warning:

Expected (inline | block | list-item | inline-block | table | inline-table | table-row-group | table-header-group | table-footer-group | table-row | table-column-group | table-column | table-cell | table-caption | box | inline-box | grid | inline-grid | none | inherit | -moz-box | -moz-inline-block | -moz-inline-box | -moz-inline-grid | -moz-inline-stack | -moz-inline-table | -moz-grid | -moz-grid-group | -moz-grid-line | -moz-groupbox | -moz-deck | -moz-popup | -moz-stack | -moz-marker) but found '-webkit-box'. Properties should be known (listed in CSS3 specification) or be a vendor-prefixed property. (known-properties)

but this property is available indeed.

Okay, thanks very much!
I'll read the contributing guide and try to add this property later.
