Analyzing this rule somewhat requires analyzing it's use for all CSS properties. It might be better to identify negative cases from use. E.g., through use we decide that we want to never use display: table-cell and then write a rule with this for display.

None are popping to mind for me that should be explicitly whitelisted.
