columns width and tabset

[antoine4ucsd]

Bug description

Hello
I am having issue when trying to have side by side columns when both contains tabset
the specified width is not considered (50/50) while if I include tabset in only one column, the width is considered (in my example 70/30)
it is probably an obvious mistake but can't figure out...

Steps to reproduce

---
title: "test tabset"
format: dashboard
---

# Test

## Row
### Column {.tabset width="70%"}

```{r}
#| title: Plt 1
library(ggplot2)
plt<- ggplot(mtcars, aes(x = hp, y = mpg, color = factor(cyl))) +
  geom_point(size = 3) +
  labs(
    title = "Random Plot: MPG vs Horsepower",
    x = "Horsepower (hp)",
    y = "Miles per Gallon (mpg)",
    color = "Cylinders"
  ) +
  theme_minimal()
plt
```

```{r}
#| title: Plt 2
plt
```

```{r}
#| title: Plt 3
plt
```

### Column {.tabset width="30%"}

```{r}
#| title: Plt 4
plt
```

```{r}
#| title: Plt 5
plt
```

Actual behavior

the width for each column is 50/50 in this example
if I remove the tabset from one column I get the expected 70/30 ratio

@antoine4ucsd avoid computations in your examples when there is no need for them.
Quarto has two shortcodes for this: placeholder and lipsum, use them.
