Under Webpack dev server, does it rebuild also if other scss are changed?

Hi,
first of all thanks for the great plugin.

I was wondering why my project takes time to serve an hot update of the css and, measuring the lag, I've found that you plugin runs also if I change another file (ex. scss) that is not included in the plugin config.

Is this true?
Is there a way to tell the plugin to run only if one of the file in the list changes?
Thanks in advance.
Marco
