Describe the Bug

When rendering a .astro component in an MDX file which is a part of a content collection, <style> tags do not look.

WORKAROUND if I manually add my custom component to the rendered (E.G. <Content components={{ StyledCard }} in my reproduction things start working. The branch linked in the reproduction does not have this so it is faithfully reproducing the error.

What's the expected result?

.astro components containing <style is:global... rendered in .mdx files should work.
