Record type doesn't show up in completion list for generic type parameter above the record declaration

If I define a `record` type, the type doesn't show up in the completion list in code before the type is defined, even though the code does build.

The screenshot is from a Razor document but the issue repros in a plain .cs file too.


The `record` type does show up in the completion list in code after the `record` type is defined.

If I define a `class` instead of a `record`, then the type shows up in completions before and after the type definition.

Start by reproducing the completion behavior in a plain .cs file, then verify whether it also occurs in the Razor document shown in the report. Compare a record declaration with a class declaration when referenced from a generic type parameter before the declaration; done means the record appears in completion results before and after its declaration.
