Sass challenge timeout

Describe the bug Sass pages with invalid syntax occasionally timeout

To Reproduce Steps to reproduce the behavior:

1. Go to https://www.freecodecamp.org/learn/front-end-libraries/sass/store-data-with-sass-variables
2. Paste in

<style type='text/scss'>
$text-color: red;

  .header{
    text-align: center;
  }
  .blog-post, h2 {
    color: $text-color;

</style>

1. See timeout in the console (sometimes)

Expected behavior

The following should appear in the console:

Error: Invalid CSS after "...r: $text-color;": expected "}", was ""
        on line 8:24 of /stdin
>>     color: $text-color;

Since this is intermittent, here’s a gif to demonstrate:

Additional Context

When the error appears it does so very quickly, so it is unlikely that this is due to a genuine timeout.

I’m currently taking a look into a possible solution on this!

While this is old, it’s still reproducible, unfortunately. A PR to improve the warning would be welcome.
