Enums and interfaces do not have definitions in quick info/tooltips

The issue might be related to this one, but mine is not about version 3.0, and is not solely about imports.

Suggestion

Hovering over enums and interfaces, should show their definition, i.e. I have this enum (or an interface):

enum enumName {
    ONE = 1;
    TWO = 2;
    THREE = 3;
}

If I hover over this enum, wherever I use it (whether it is imported to another file or used locally where it is declared), I would like to see what this enum is all about (essentially what are the properties).

This is what I see right now when I hover over enums or interfaces:

As a workaround, I currently need to add this type of JSDoc comments right above the enum declaration.

/** Props:
*    @param ONE 1;
*    @param TWO 2;
*    @param THREE 3;
*/

Which yields to:

Use Cases

This feature would save time & effort.
The shortcoming of the current approach is that either need to add ${2+numberOfEnumProperties} lines of comments or go to the file, where enum is declared, locate the enum there and then familiarize myself with its properties.

Checklist

I am not that experienced to be able to answer the questions below.

• This wouldn't be a breaking change in existing TypeScript / JavaScript code
• This wouldn't change the runtime behavior of existing JavaScript code
• This could be implemented without emitting different JS based on the types of the expressions
• This isn't a runtime feature (e.g. new expression-level syntax)

Issue に記載された enum と interface の例を使って、報告された quick-info の動作を、ローカルの場合とインポートした場合の両方で再現します。まず TypeScript の quick-info/tooltip エントリーポイントをたどり、次にこれらの宣言に対する既存の表示動作を特定します。ホバー時に、ローカルでの使用とインポートした場合の使用の両方で、それらの定義とメンバーが表示され、関連するテストが更新されていれば完了です。
