R Plotly multi line tooltip - text outside the box

Question

I'm having troubles while plotting multiline tooltips in R Plotly (R package version: 4.7.1). The tooltip is not formatted correctly. Text goes outside the tooltip background.

Minimal example:

This can be replicated by running the following code:

data <- matrix(c(1:16), ncol = 2)
# Plot the chart
plot_ly(
    x = c("a", "b"),
    y = c(letters[1:8]),
    z = data,
    showscale = FALSE,
    hoverinfo = 'text',
    text = matrix(rep("Lorem ipsum dolor sit amet,<br>consectetur adipiscing elit,<br>sed do eiusmod tempor<br>incididunt ut labore et dolore<br>magna aliqua.<br>Ut enim ad minim veniam, quis<br>nostrud exercitation ullamco laboris nisi<br>ut aliquip ex ea commodo consequat.<br>Duis aute irure dolor in<br>reprehenderit in voluptate velit esse<br>cillum dolore eu fugiat nulla pariatur.", 16), ncol = 2),
    type = "heatmap"
)

This effect is only achievable if you resize the browser window. In my real case I have it in a Shiny app so the space is limited. However, it seems that there is enough space to plot tooltip correctly. Any ideas how to fix this?

Updating plotly to 4.8 indeed solves the problem.
