Plotly hover tooltips only work on the last sticky plot in a .cr-section

[pensivedog]

When using multiple Plotly charts as sticky figures inside a single .cr-section, hover tooltips stop working for all charts except the last one. Only the final sticky plot in the section shows interactive hover information.

This happens with plain plotly::plot_ly() as well as ggplotly(), and appears to be related to how Closeread manages sticky containers.

Steps to reproduce

Create a minimal Quarto document using closeread-html and multiple sticky Plotly charts:

---
title: "Closeread + Plotly hover test"
format: closeread-html
execute:
  echo: false
  warning: false
  message: false
---

:::{.cr-section}

Hover over the points on the right and note there is no hoverinfo. @cr-plot1

:::{#cr-plot1}
```{r}
library(plotly)

plot_ly(
  data = mtcars,
  x    = ~hp,
  y    = ~mpg,
  type = "scatter",
  mode = "markers"
)
```
:::

Now hover over the points on the right and note the hover info works properly. @cr-plot2

:::{#cr-plot2}
```{r}
library(plotly)

plot_ly(
  data = mtcars,
  x    = ~wt,
  y    = ~mpg,
  type = "scatter",
  mode = "markers"
)
```

Expected behavior

All sticky Plotly charts should show hover tooltips when mousing over data points.

Actual behavior

Only the last Plotly chart in the .cr-section shows hover tooltips. Earlier sticky plots do not respond to hover.
