Steps to Reproduce:

I have an Angular project, and just 1 of the files don't have a proper suggestion support in it.
Same happens when I create a file via plus sign from the side bar.
VSCode doesn't suggest "obvious(necessary)" things, quite the contrary happens:
it suggests everything else what's available, but not what I need and not what really exists in the project.

Also, when I try to import environment object with 'src/environments/environment',
it doesn't seem to know about src folder(project_name/src).
Although it already works this way for all the other files in the project.

Cache cleaning && insiders build didn't help out, no errors in debug console and I couldn't find any useful tsserver logs.
Although I can send if necessary.

Does this issue occur when all extensions are disabled?: Yes

まず、報告された Angular のプロジェクト参照設定を VS Code で再現し、参照先のシンボルが他の場所でまだ import されていない状態での自動 import 候補に焦点を当てます。issue ではリポジトリのファイルやテストは指定されていません。完了条件は、src/environments/environment を含む参照先プロジェクトからの import が、新しく作成したファイルで一貫して候補に表示されることです。
