Describe the Bug

File src/components/A.js is a lit component with a custom converter for the attribute 'text'. This converter should convert the attribute given as text to the length of the text. This converter is not called.

What's the expected result?

The converter should be called and the rendered text should be "6" instead of "AAAAAA".

Quick and dirty test. Sorry for the screenshots.

Some observations:

• Properties are not serialized at all, independently of the Lit converter thing. This is weird, I don't remember such a glaring issue.
• Loading MyTest once, and subsequently, <my-test> will me picked up and rendered as such.
• Removing MyTest import, restart server, Astro's Custom Element Registry implementation doesn't pick up <my-test> anymore.
• Import the component in a client script tag, and the client component is picked up again, this time with the serialized attributes. Wut?

This is not very scientific, just poking around. I don't fully understand what is going with these discrepancies.

In 5.0, we removed the Lit integration so we don't plan to address this issue. If you’re interested in maintaining a Lit integration yourself, you may wish to use the last published version of @astrojs/lit as a starting point and upgrade the relevant packages.
