REGRESSION (r198990): Cannot edit content inside <details> in wysiwyg editor
https://bugs.webkit.org/show_bug.cgi?id=165757

Reviewed by Andreas Kling.

Test: fast/html/details-edit.html

-webkit-user-modify is reset on shadow boundary so it doesn't go through <details> shadow tree.

    Make -webkit-user-modify (which we would want to get rid of completely eventually) have no effect in shadow trees.
    Check for contenteditable directly instead.

    Let -webkit-user-modify inherit through shadow boundary as normal.
