Issue Summary

Inserting a link to external site particularly kibana URLs converts the link to http://#

Steps to Reproduce

1. Edit a Confluence page
2. Select existing text on the page
3. Use the Link command to add a link to the selected text
4. Paste a long URL as the link URL. Example:

   https://kibana-production.example.com/_plugin/kibana/app/kibana#/discover?_g=(refreshInterval:(display:Off,pause:!f,section:0,value:0),time:(mode:absolute,from:'2020-04-15T14:00:00%2B00:00',to:'2020-04-17T14:13:09%2B00:00'))&_a=(columns:!(_source),index:'32d3f490-a60c-11e8-aafa-29a6e8a01ca8',interval:auto,query:(language:lucene,query:(query_string:(analyze_wildcard:!t,query:'extra.request.headers_size_kb:%3E6'))),sort:!(es_time,desc)

5. Publish the page
