Purchase.cart-line-item.line-components.render extension point is not showing up in the customiser

[Bas-code]

Describe the bug

I am trying to enable a purchase.cart-line-item.line-components.render extension in the customiser after deployment of the extensions. But it keeps saying that the app block is not available. In development mode the extension is working fine. I tested this with a really clean UI extension point.
Other extension points like 'purchase.checkout.cart-line-item' are working fine.

Steps to reproduce the behavior:

1. Create a new checkout UI extension
2. Change the extension point in the toml and javascript file of the extension
3. Run npm run dev to check if the extension is showing in a development checkout.
4. Run npm run deploy to release a new version of the app
5. After install it is not possible to enable the extension in the customiser.

Expected behavior

When you can enable a 'purchase.checkout.cart-line-item' it should also be possible to enable 'purchase.cart-line-item.line-components.render' in the customiser.
