# Context
We have recently migrated from workspace.views to core.views. While
doing it, we've lost the optimistic rendering on views in frontend. This
is an issue for viewField and viewGroups that are persisted without
having an intermediate storing layer (viewFilters, viewSorts,
viewFilterGroups are not directly persisted when we do the changes,
therefore we have an underlying layer to keep them and the optimistic
was implemented there already).
ViewFields have been treated in a previous PR, this PR focus on
ViewGroups
## What
Optimistic on ViewGroups
## Other
+ fix a bug in the sequencing to persist viewFilter + viewFilterGroups
