Mark Slow: console-format.html,heap-snapshot-containment-expansion-preserved-when-sorting.html,heap-snapshot-containment-sorting.html

Since enabling selection for web components, selection traverses composed tree

 - console-format.html
 - heap-snapshot-containment-expansion-preserved-when-sorting.html
 - heap-snapshot-containment-sorting.html
