LSP: auto import doesn't work correctly with project-root-for-absolute-imports mapping

[GuyBorderless]

Version: Deno 1.43.4 (but occurs with older versions too)
If the project root is mapped for absolute imports with

{
  "imports": {
    "/": "./",
    "./": "./"
  }
}

The LSP incorrectly auto-imports from files in subdirectories.
Here is an example repo

The LSP imports from a non-existent path
import { ImportFn } from "./importme.ts";
Instead of
import { ImportFn } from "/importme.ts";
