BioCircos plots render layers incorrectly in Dashboard

Bug description

Hello, I recently changed my reports from using FlexDashboard to Quarto dashboard and there is a noticeable difference in behavior for plots made with BioCircos. Namely, the hover tooltip is hidden beneath the plot, which was not an issue when it rendered in FlexDashboard.

Steps to reproduce

---
title: "BioCircos Test"
execute:
    echo: false
    warning: false
embed-resources: true
format:
  dashboard:
    theme: lumen
    scrolling: true
    expandable: false
---

```{r}
library(BioCircos)
```

# Page 1
## text
Here is some text. Lorem ipsum etc.

```{r}
# Chromosomes on which the points should be displayed
points_chromosomes = c('X', '2', '7', '13', '9')
# Coordinates on which the points should be displayed
points_coordinates = c(102621, 140253678, 98567307, 28937403, 20484611) 
# Values associated with each point, used as radial coordinate 
#   on a scale going to minRadius for the lowest value to maxRadius for the highest value
points_values = 0:4

tracklist = BioCircosSNPTrack('mySNPTrack', points_chromosomes, points_coordinates, 
  points_values, colors = c("tomato2", "darkblue"), minRadius = 0.5, maxRadius = 0.9)

# Background are always placed below other tracks
tracklist = tracklist + BioCircosBackgroundTrack("myBackgroundTrack", 
  minRadius = 0.5, maxRadius = 0.9,
  borderColors = "#AAAAAA", borderSize = 0.6, fillColors = "#B3E6FF")  

BioCircos(tracklist, genomeFillColor = "PuOr",
  chrPad = 0.05, displayGenomeBorder = FALSE, yChr =  FALSE,
  genomeTicksDisplay = FALSE,  genomeLabelTextSize = 18, genomeLabelDy = 0)
```

Actual behavior

The tooltip is behind all the rendered plot components

Expected behavior

The tooltip rendering works correctly in the VSCode Viewer tab and when the QMD is rendered as an HTML document:

Start by rendering the supplied BioCircos example as a Quarto dashboard and compare its tooltip layering with the HTML document and VSCode Viewer. Investigate the dashboard rendering path to identify why the tooltip appears beneath plot components; done means the tooltip is visibly above the rendered plot.
