Module context export not working if instance variable with same name exists

[klaussner]

Describe the bug

If a variable is exported from a module context and a variable with the same name is declared in a <script> element, the export is omitted from the module.

<script context="module">
  export const x = 1;
</script>

<script>
  const x = 2;
</script>

To reproduce

Svelte REPL: https://svelte.dev/repl/0935c4be70ff446989a0517c28394e58?version=3.15.0

Expected behavior

The compiled module should have two exports: the default component export and the module context export:

export default App;
export { x }; // This line is missing!

Information about your Svelte project

• Svelte version: 3.15.0

Severity

This issue can easily be avoided by giving the variables different names.

It looks like the bug was introduced in 3.13.0. Version 3.12.1 generates an export for x: https://svelte.dev/repl/0935c4be70ff446989a0517c28394e58?version=3.12.1.
