Nautilus 45 headerbar issue

[wangxa]

The headerbar of the place sidebar has 6px gap with the toolbar of the main window of Nautilus. See the following image.

After browsing the source code of libadwaita, I found this is caused by the CSS style:

toolbarview .collapse-spacing {
  padding-top: 3px;
  padding-bottom: 3px;
}

If you set these paddings as 0, the issue will be resolved.
