Extracting text from template strings with interpolation does not work properly in pure JS files

[FelixGraf]

Describe the bug

When having the following code snippet in a pure JS file and trying to extract the ´Hello ${test}´ part, it does not transform the test variable into a parameter {0} but instead the output in the JSON file is just "Hello ${test}". When doing the same within the <script> of a Vue SFC, it works without problems. (Also see the attached screen recording)

const test = 123;
const hello = `Hello ${test}`;
