| The bug is that the CSS Regions feature leaks information at run-time. There are JS properties that exist even |
| if the feature is disabled at run-time (document.webkitGetNamedFlows, document.body.webkitRegionOverset, |
| document.body.webkitGetRegionFlowRanges and window.WebKitCSSRegionRule). |
| The best LayoutTest would test that the properties exist when the feature is enabled and that the properties |
| just aren't there when the feature is disabled. |
| But, since during running Layout Tests the feature is enabled by default and switching the |
| RuntimeEnabledFeatures requires the process to be restarted and that is currently not possible, we can only test |
| that the properties exist and have the proper type. |
| On success, you should see a series of PASS messages. |
