ordered list always centered in custom float

Bug description

If I make a custom float, (ordered) lists are always centered (they inherit from quarto-figure-centered for some reason). Tried to overwrite this centering with different css tags, but they all get ignored.

Steps to reproduce

Example qmd:

---
title: "Bug report"
format: 
  html:
    css: doesntwork.css
crossref:
  custom:
    - kind: float
      reference-prefix: Exercises
      key: exercises
      caption-location: top	
---

## An example

make exercises @exercises-exercises-1

:::{.exerc #exercises-exercises-1}
1. A first exercise.
2. A second exercise.
:::

WIth the following css:

.exerc{
  background-color: rgb(247, 247, 247);
  align-items: left;
  text-align: left;
  align-content: left;
  align-self: left;
}

The background color shows, but all the rest is doing nothing.

Expected behavior

The ordered list in exercises should be left aligned

Actual behavior

The ordered list in exercises is centered
