Google not indexing pages due to "Duplicate without user-selected canonical" issue

### Link to the code that reproduces this issue https://github.com/jperezr21/static-and-dynamic-metadata ### To Reproduce 1. Create dynamic path with async `generateMetadata` that sets `alternates.canonical` to the path without any query params (let's say `/[storeHandle]/[productSlug]`). 2. Have a selectable property that's reflected in the URL query params (eg: `?variant=[variantName]`) 3. Have other pages link to the page with the query params (eg: link to specific product variants). 4. Google will say there's no user-selected canonical for these pages even though it is (the problem is that the canonical tag is being streamed and it's not present in the initial HTML).   ### Current vs. Expected behavior - Current: Google is not detecting user-selected canonical for streamed pages - Expected: Have the ability for defining both static and dynamic metadata. I want to have the canonical as static, but the rest (product title, description, images, etc) dynamic. This isn't supported at the moment (from the docs): > You cannot export both the metadata object and generateMetadata function from the same route segment. ### Provide environment information ```bash Operating System: Platform: darwin Arch: arm64 Version: Darwin Kernel Version 24.5.0: Tue Apr 22 19:54:29 PDT 2025; root:xnu-11417.121.6~2/RELEASE_ARM64_T6030 Available memory (MB): 18432 Available CPU cores: 11 Binaries: Node: 22.13.1 npm: 11.1.0 Yarn: N/A pnpm: 10.12.1 Relevant Packages: next: 15.3.4 // Latest available version is detected (15.3.4). eslint-config-next: N/A react: 19.1.0 react-dom: 19.1.0 typescript: N/A Next.js Config: output: N/A ``` ### Which area(s) are affected?
