base64 string is broken with v1.8.4

[rivancic]

Description

I wrote build script with gulp. One of the steps was to prettify the scss code. I used [email protected]
which has a dependency on js-beautify.
When the build process runs with the [email protected] sass processor does not throw any issues in next step. But with the update of the dependency to [email protected] the sass procesor step is broken. I was not using any settings for js-beautify lib. But per default previous version was working. Is it neccessary to provide now additional settings?

Error message is as following:

[10:39:48] Starting 'sass'...
Error in plugin 'sass'
Message:
    assets/scss/сomponents/_sorting.scss
Error: Invalid CSS after "...round: url(data": expected expression (e.g. 1px, bold), was ":image/gif;"
        on line 16 of assets/scss/сomponents/_sorting.scss
        from line 19 of assets/scss/style.scss
>>   background: url(data:image/gif;

   ------------------^
[10:39:51] Finished 'sass' after 3.3 s

I compared the output of both versions for the specific _sorting.scss file

Input

background: url(data:image/gif;base64,R0lGODlhCwALAJEAAAAAAP///xUVFf///yH5BAEAAAMALAAAAAALAAsAAAIPnI+py+0/hJzz0IruwjsVADs=);

Expected Output

Output of [email protected] 👍

background: url(data:image/gif;base64,R0lGODlhCwALAJEAAAAAAP///xUVFf///yH5BAEAAAMALAAAAAALAAsAAAIPnI+py+0/hJzz0IruwjsVADs=);

Actual Output

Output of [email protected]

 background: url(data:image/gif;
  base64, R0lGODlhCwALAJEAAAAAAP ///xUVFf///yH5BAEAAAMALAAAAAALAAsAAAIPnI+py+0/hJzz0IruwjsVADs=);

Now the sass processor is broken because of the spaces in the base64 string representation

Steps to Reproduce

Environment

OS: Linux

Settings

I was using default settings.

The problem is in the logic here: https://github.com/beautify-web/js-beautify/blob/master/js/src/css/beautifier.js#L373

Tests for the uri format inside url(<uri>) don't sufficiently cover this format to ensure it doesn't break.

Format details can be found here:

Thanks @bitwiseman for the fixing the issue in such a short time. Respect!
I upgraded version to 1.8.6 and I can confirm now the formatting is correct. 👍
