Components that inherit from another class do not render with the appropriate CSS class

[kino-pi]

Description

I have defined a few components like so:

tag my-component
	css w:fit-content h:fit-content
		bg:cool9 c:cool1
		p:1rem 2rem
	<self>
		<slot>

tag my-button < button
	css w:fit-content h:fit-content
		bg:cool9 c:cool1
		p:1rem 2rem
	<self>
		<slot>

tag my-div < div
	css w:fit-content h:fit-content
		bg:cool9 c:cool1
		p:1rem 2rem
	<self>
		<slot>

Expected behavior: Components that extend another class should render with the defined CSS styles.

Actual behavior: Components are not being styled.

Firefox inspector showing the lack of compiled CSS classes on both the button and div components

Other notes:

• Running the project with the --web command line flag npm run dev -- --web results in the expected behavior.
• Defining a class on <self> like <self.anything> on each component results in the expected behavior.
