Web Inspector: [Backend] Page.searchInResources sometimes returns duplicate results for a resource

Steps to Reproduce:
1. Inspect <https://www.cio.com>
2. Search for "touchMoved:"
3. May require a reload + research to trigger this issue
  => Page.searchInResources result sometimes includes select2.js multiple times

Logs:

    [Log] request: {"id":795,"method":"Page.searchInResource","params":{"frameId":"0.4","url":"https://www.cio.com/www.idge.ans/js/select2-3.5.0/select2.js","query":"touchMoved:","caseSensitive":false,"isRegex":false}} (Main.js, line 941)
    [Log] request: {"id":796,"method":"Page.searchInResource","params":{"frameId":"0.4","url":"https://www.cio.com/www.idge.ans/js/select2-3.5.0/select2.js","query":"touchMoved:","caseSensitive":false,"isRegex":false,"requestId":"0.972"}} (Main.js, line 941)

Notes:

  • PageAgent::searchInResources searches cached resources
  • NetworkAgent::searchOtherRequests searches NetworkData data, such as XHRs and Worker scripts

Apparently we are hitting the same resource multiple times. How can the backend avoid this duplicated work?
