GEN-PLAIN and GEN-XSS not inserting into input fields

[for-indy]

Using version 0.6, when I click n the owl and select GEN-PLAIN or GEN-XSS, nothing happens in the browser, but I see a new payload pop up each time in the Tracy web UI. The zz payloads will insert into the input but not the GEN.

I see no errors in the terminal Tracy is running in when I try these inputs, but in the Javascript console in the web tools in Chrome I see SyntaxError: Unexpected end of JSON input, then below that Cross-Origin Read Blocking (CORB) blocked cross-origin response http://localhost:7777/api/tracy/tracers/generate?tracer_string=GEN-XSS&url=https://www.w3schools.com/html/html_forms.asp with MIME type text/plain.

Per our discussion in person, I believe this is due to Chrome's new stance on CORS requests from within a content script. More info is here:

We need to move the fetch requests out of the content script and into the background page.
