Issues with metadata of `material_ui`

The "View/report issues" link on https://pub.dev/packages/material_ui goes to a Github issue search for a label that doesn't exist.

Also, when hitting "New issue" in this repository, the "Report a bug in one of Flutter's first-party packages" template asks "What package does this bug report belong to?", and states the following:
> If the package you are reporting a bug for is not listed here, it could be a third party package's issue. In that case, you should report the issue to the package's developers.

However, despite `material_ui` obviously being a first-party package, it is not included there.

Inspect the metadata for the material_ui package and the repository's "Report a bug in one of Flutter's first-party packages" issue template. Verify how the pub.dev "View/report issues" link is generated and where first-party packages are listed. Done means the link uses an existing label and material_ui appears in the template's package list.
