If you have more than 7 "Saved Objects" in Kibana 7.3.0 you can't delete them. After pressing "Delete", the browser window is stucked on an endless Kibana logo jumping animation.
Steps to reproduce:
- Create an index pattern
- Create 6 visualizations e.g. Metric visualization
- Go to Management -> Kibana Saved Objects -> you will have 8 objects shown
- Select them all
- Press Delete button
I opened an issue for this problem https://github.com/elastic/kibana/issues/42426.
