Can I report a glitch in Customizer?

Empire theme happens to use a class page-content.

Trying to style it with “Custom CSS” fails:

.page-content {
  max-width: none;
}

I can guess where it’s coming from, but obviously a false positive.

@Alan_G or @Liam-Shopify ?

Hey Tim - is this happening with just the Empire theme? If so, the best option would be to flag it to their team here: https://support.pixelunion.net/hc/en-us/requests/new

Of course not, it just happens that they have this class name in their theme.

If I try using this CSS code in Dawn (which does not have this class itself, but, say product description may have it) the error message is the same.
