Issue Reporter cannot be used in dev builds

System details:

Positron and OS details:

This was discovered when testing https://github.com/posit-dev/positron/pull/5981 which is based on the prerelease/2025.01 branch, however, the issue can be reproduced on main (currently @ fe3a53cc63e640d8695849e17cd9cea667406bf6) as well.

I think we'll need to step through commits from 2bc1b74aba437cd10126eb098b56a5911786868b and earlier to see when this issue was first introduced. This commit is when we branched from main to create the prerelease/2025.01 branch.

Interpreter details:

Any

Describe the issue:

In dev builds (at least Mac and Windows), the Issue Reporter can be opened, but is blank and an error occurs. It is not possible to send an issue report through the Issue Reporter.

Interestingly, Jonathan noted that when using the debugger to step through the dev build, the Issue Reporter works fine!

Release builds don't have this issue.

Steps to reproduce the issue:

1. Open a dev build of Positron Desktop on Mac or Windows
2. Click on Help in the top bar, then Report Issue
3. The Issue Reporter opens, but is blank and an error shows

Expected or desired behavior:

The Issue Reporter should show the issue submission form and no error should occur.

Were there any error messages in the UI, Output panel, or Developer Tools console?

Mac

No errors in the Dev Tools console, but the error notification shows:

Failed to execute 'invoke' on 'CreateHTMLCallback': The provided callback is no longer runnable.

Windows

No notification error, but the Dev Tools console includes:

Reproduce the blank Issue Reporter from Help > Report Issue in a Mac or Windows dev build, then inspect the reported CreateHTMLCallback and Titlebar overlay errors. Compare behavior with a release build and step through the relevant desktop window and reporter entry points. Done means the submission form opens without errors in dev builds on both platforms.
