webview-codicons broken when packaged

Extension sample

webview-codicons-sample

VS Code version

1.98.2

What went wrong?

The webview-codicons-sample works fine in the local "Run Extension" debugging mode. However, when the extension is packaged and installed using vsce package and code --install-extension, the crucial codicon.css file is not loaded with a 404 error. This causes none of the icons to be displayed.

This extension sample should still function when packaged/installed to serve as an example for how webviews can use vscode's native codicons.

I figured out my problem thanks to Issue#692. While the sample extension works, I got confused because the standard .vscodeignore setup excludes all node_modules/** files from the packaged .vsix.

It would be great if this sample could add a .vscodeignore file, demonstrating the necessity of having something like the following:

node_modules/**
!node_modules/@vscode/codicons/dist/codicon.css
!node_modules/@vscode/codicons/dist/codicon.ttf
