interactView does not handle edit events
Some editors require the processing of edit events even though the task is technically a "view" task.
For example, SVG editors need to send text metrics and Leaflet maps send viewport measurements.
interactView task introduced by the async shares merge simply ignores edits. The
interactView tasks should be changed to a something like
interactReadWrite to indicate whether they need a writable SDS, instead of being based on view/update mode.
