Abstract classes will still import the value for a computed property at runtime

TypeScript Version: 3.7.0-dev.20190920

abstract class import computed property
abstract class computed property imports for runtime

Code
sharedSymbol.ts

export const sharedSymbol: unique symbol = Symbol();

AbstractClass.ts

import { sharedSymbol } from "./sharedSymbol";

abstract class AbstractClass {
    public abstract [sharedSymbol]: string;
}

Expected behavior:
sharedSymbol.js is not imported by AbstractClass.js
Actual behavior:
The symbol is imported by AbstractClass.js despite it's use being omitted due to it's abstract nature

Playground Link: Unavailable due to the bug being related to imported values.

Reproduisez le problème avec sharedSymbol.ts et AbstractClass.ts, puis examinez le AbstractClass.js généré et la gestion par le compilateur des propriétés calculées abstraites. Ajoutez un test de régression pour la valeur importée et vérifiez que le JavaScript généré n’importe plus sharedSymbol.js.
