resource_load_base_uri property Leave feedback

The base URI used to resolve external resource files’ relative URIs to absolute ones when loading an HTML template document to be assembled and saved to a non‑HTML format. The default value is an empty string.

When loading an HTML document from a file, its containing folder is used as a base URI by default, which cannot happen when loading an HTML document from a stream. Set this property to specify a base URI when loading an HTML document from a stream or to override the default base URI when loading an HTML document from a file.

A value of this property is ignored in the following cases:

• An HTML document being loaded contains a BASE HTML element providing a base URI.
• An HTML document being loaded is to be assembled and saved to HTML (external resource files are not loaded and relative URIs are not changed then).
