Observable Plot doesn't render properly inside tabset panel

[agre689]

Bug description

OJS plots don't display properly inside tabset panels of my dashboard when the document is rendered.
I think the plot might be rendering at a height ~0px?
If I click "Expand" the expanded plot is displayed, and if I close the expanded window, the plot displays as it should. Navigating away from this tab resets the plot and the plot is collapsed again.
I see this behaviour in RStudio's viewer pane as well as in Chrome and Firefox.

Steps to reproduce

---
title: "Untitled"
format: dashboard
---

```{r}
#| output: false

df = data.frame(x = 1:10, y = 1:10)
ojs_define(df)
```

# Page

## Page Content

::: {.panel-tabset}

### Plot1

```{ojs}
Plot.plot({
  marks: [
    Plot.lineY(transpose(df), {x: "x", y: "y"})
  ]
})
```

### Plot2

Expected behavior

Plot is displayed at normal height on opening the document.

Actual behavior

Plot is minimised/not rendered (?) until expanding and closing the plot window.
