Shared document groups: automation and match fixes

Automations now run correctly on imported document groups. When a document group is shared with your workpaper from another workpaper in the engagement, running automations — including testing attributes and run-all — now operates on your workpaper's data. Previously, these operations could silently target the original owning workpaper and produce no output.
Workpaper grid no longer shows blank rows after automation runs. If your workpaper uses an imported document group, running a full automation could cause rows to disappear from the grid. This is now fixed.
Match accept operations apply to the correct workpaper. Accepting file or record matches on a shared document group now correctly records results under the workpaper you are working in, not the workpaper that owns the document group.
Live updates now refresh the correct workpaper. When an automation clears or updates a shared document group, the refresh now appears on the workpaper you are viewing rather than the owning workpaper.
