Only add ! to selector class matching template candidate (#7664)
* Only add `!` to selector class matching template candidate

Fixes #7226.

Before this PR, if you had a class like:

```css
.one .two {
  background: black
}
```

...and then used `!one` in your template, the generated CSS would be this:

```css
.\!one .\!two {
  background: black !important
}
```

This would cause the styles to not be applied unless you also added `!` to the beginning of other classes in the template that are part of this selector.

This PR makes sure that other classes in the selector aren't mistakenly prefixed with `!`, so that you can add `!` to only one of the classes in your template and get the expected result.

* Update CHANGELOG
