Feature request: support pauses in revealjs presentations in slides with multiple columns

Would it be possible to support "pauses" in revealjs presentations in slides that have multiple columns? I would like to show first one column, and after a click, the other.

E.g. the following does not work:

---
format:
  revealjs:
    center: true
---

## The ASIA network {.smaller}

:::: {.columns}

::: {.column width="60%"}

| **Random variable**  | **Meaning**                     |
|        :---:         | :---                            |
|        ``A``         | Recent trip to Asia             |
|        ``T``         | Patient has tuberculosis        |
|        ``S``         | Patient is a smoker             |
|        ``L``         | Patient has lung cancer         |
|        ``B``         | Patient has bronchitis          |
|        ``E``         | Patient has ``T`` and/or ``L``  |
|        ``X``         | Chest X-Ray is positive         |
|        ``D``         | Patient has dyspnoea            |

Start by reproducing the supplied Markdown example as a revealjs presentation and verify how the pause markers behave inside the two-column layout. Trace the revealjs column and pause handling to identify the boundary, then confirm that the first column appears before a click and the second appears afterward.
