Description Martin Robinson 2022-03-02 04:17:49 PST 
Under certain circumstances, when a snap area covers the viewport the user should be able to scroll into the middle of the area without triggering a snap. An exception to this rule is when doing a directional snap into the large scroll area. In that case, if there is an intermediate snap point (one from another element) that is between the start and end of the large snap area, the scroll should not skip past this intermediate point.

This patch modifies the imported WPT tests. Please ensure that any changes on the tests (not coming from a WPT import) are exported to WPT. Please see https://trac.webkit.org/wiki/WPTExportProcess

Clearing flags. The script used to focus elements for key events needs a bit more work.
