[Fix for #12121] Update dashboard based on url changes #12123
- We fixed a bug where certain modifications made directly to the dashboard url, such as changing panel sizes and modifying the query, failed to update dashboard without a hard refresh.
[Fix for #11925] [context view] Use _doc for tie-breaking instead of _uid #12096
- To avoid filling up Elasticsearch’s fielddata cache by sorting on the _uid field in the context view, the field _doc is now used as a tiebreaker by default. The field to be used can now be configured using the context:tieBreakingFields advanced setting.
