Problem

As you can see here, JavaScript syntax highlighting does not work for Pug attributes that use template literals:

The syntax highlighting works correctly with single quotes and escaped newlines:

Reproducible Case

Create a Vue file with the following code:

<template lang='pug'>
  .list(
    :options=`[
      {
        name: "Main"
      },
      {
        name: "Crypto"
      },
      {
        name: "Stocks and stuff haha"
      }
    ]`
  )
</template>
