Structured CSS selector to use for custom element's host.

It modifies the selectors of produced CSS rules.

For custom element with shadow root:

• Replaces root CSS rule selector with `:host().
• When hostSelector is omitted, then replaces root CSS rule selector with :host.
• If CSS rule selector starts with :host, then replaces :host with :host(<hostSelector>)
• If CSS rule selector starts with :host(<selector>), then extends <selector> by hostSelector. I.e. appends CSS classes and sub-selectors to it, and fulfills missing element and identifier selectors.

For custom element without shadow root either uses provided hostSelector, or generates a unique one when omitted. And additionally:

• Replaces root CSS rule selector it with hostSelector.
• If CSS rule selector starts with :host, then replaces :host with hostSelector.
• If CSS rule selector starts with :host(<selector>), then replaces :host()withextended byhostSelector`. I.e. appends CSS classes and sub-selectors to it, and fulfills missing element and identifier selectors.
• Otherwise prepends CSS rule selector with hostSelector.

This selector should not contain a :host sub-selector.

Namespace aliaser to use.

Default NamespaceAliaser used when omitted.

Root CSS selector is never used for custom elements. A hostSelector is applied instead.
