@webext-core/messaging errors with No response when sending data back from an injected script

[rcoopr]

Using only example code from the webext-core site, injected script messaging causes an error (No error when sending messages to the injected script) Potentially related to #55 ?

Error:

Uncaught (in promise) Error: No response
    at Object.<anonymous> (chunk-ALTBYIMW.js:80:67)
    at Generator.next (<anonymous>)
    at fulfilled (chunk-ALTBYIMW.js:36:24)

Minimal repro: https://github.com/rcoopr/wxtcore-messaging-repro

• clone
• pnpm i
• pnpm dev
• check console

What steps did I do to create example:

• init WXT using pnpm dlx wxt@latest init <project-name>
• pnpm i @webext-core/messaging
• Add permissions for injected script to wxt config
• Copy code from https://webext-core.aklinker1.io/guide/messaging/#window-messaging (Also, there is a typo, browser.runtime.getUrl is actually getURL)
• run pnpm dev and check console

The messages are recieved, yet there is an error anyway. The issue is also present in the built output. Only tested on Chrome 122
