* SUMMARY
Background Tabs waste a lot of time on reload populating editor content.
* STEPS TO REPRODUCE
1. Inspect webkit.org
2. Resources > select a resource
3. Debugger > select a different resource
4. Show Console Tab
5. Reload
=> ~300ms of frontend time (85%) is spent populating source code text editor content for the resources in the background tabs
* NOTES
- It may be fine for the background tabs to fetch the content, but not to process it!
- See attached screenshot for a profile</pre>
