Multiline / linebreak in tbl-cap is not supported

Bug description

The second table does not render correctly:

---
title: "Empty"
engine: jupyter
---

```{python}
#| label: tbl-test1
#| tbl-cap: Test1

import pandas as pd

pd.DataFrame(dict(x=[10,20,30]))
```

```{python}
#| label: tbl-test2
#| tbl-cap: >
#|   Test2

import pandas as pd

pd.DataFrame(dict(x=[10,20,30]))
```

```{python}
#| label: fig-test3
#| fig-cap: >
#|   Test3

import pandas as pd

pd.DataFrame(dict(x=[10,20,30]))
```

Steps to reproduce

render the above example to HTML or PDF using the Jupyter engine

…or look at https://github.com/winniehell/quarto-playground/blob/9b084a0f9339394c0687bf7d0cc58eb215ce70be/test-book/_book/test-book.pdf (you will need to scroll down)

Expected behavior

second table is rendered with caption

Actual behavior

multiline caption / linebreak causes problem (only for table, not for figure)

also this warning is shown:
