The new index details page is not working when the index name contains special characters, for example %.
To reproduce

1. Start Kibana with details page enabled in the config/kibana.dev.yml file: xpack.index_management.dev.enableIndexDetailsPage: true
2. Create an index in Dev Tools Console PUT test_index%
3. Navigate to Index Management and click the index name to open the index details page

The page should be displayed correctly and all tabs should be working. Currently, the page is not loading.
