Figure inside .column-screen steals that class

Bug description

When we place an image with a caption inside a fenced div with .column-screen, the image gets .column-screen and the section does not, which causes various kinds of layout havoc (the rest of the section doesn't get the enlarged width, and .page-columns propagates up from the image through the rest of the document, which makes placing one's own CSS grids inside the section extremely difficult).

Steps to reproduce

Test case: https://github.com/jimjam-slam/test-quarto-cr-img-classes

---
title: Test test test
format: html
---

Oh hello! Here are some images with classes:

::::{.column-screen}

This text is inside the section. But the section itself doesn't seem to get `.column-screen`...

:::{#working}
This works: ![a caption](trees.png)
:::

This also works (no caption):

:::{#alsoworking}
![](trees.png)
:::

But this doesn't:

:::{#notworking}
![This one is breaks things](trees.png)
:::

::::

Expected behavior

The fenced div in the input document that has .column-screen should have it in the output HTML, and the image inside #notworking should not. The other ancestors of the image should also not have .page-fill .page-columns.

Actual behavior

The image receives .column-screen and goes to full width. Other elements in the section don't. Any nested grids declared inside the broken section tend to get overridden, as .page-columns is on all ancestors of the image inside.
