The siteTitleFormat.includeSiteTitle setting shows site title instead of current page title (instead of My Website - Home Page, My Website)

[silviubogan]

Describe the bug

In the link below, navRootTitle is the title of the page, never the title of the site, but still it is used in this way:

volto/packages/volto/src/components/theme/ContentMetadataTags/ContentMetadataTags.jsx

Line 70 in adfd531

const titlePart = navRootTitle || siteRootTitle;

If I comment out like this: /* navRootTitle || */, it works well.

Without this comment, since the titlePart !== title condition:

volto/packages/volto/src/components/theme/ContentMetadataTags/ContentMetadataTags.jsx

Lines 72 to 76 in adfd531

	if (includeSiteTitle && titlePart && titlePart !== title) {
	return seo_title || `${title} ${titleAndSiteTitleSeparator} ${titlePart}`;
	} else {
	return seo_title || title;
	}

is not met, the tab title is made of the website title alone.

To Reproduce
Steps to reproduce the behavior:

1. Create a Cookieplone project
2. In the add-on install function, put

   config.settings.siteTitleFormat.includeSiteTitle = true;

3. See the wrong tab title in the browser's Volto tab.

Expected behavior

I expected that the tab title contains both the website title and the current page title.
