The problem appears on Safari 13.0.3 on macOS 10.15.1 (Catalina) but interestingly does NOT occur on Chrome Version 78.0.3904.108. Possibly related to this issue ?

Here's a video of the problem in action (the plot actually flashes):

Here's the code to cause the crash (actually most plots have this behaviour). Just copy this into a JupyterLab notebook and run the cell:

options(tidyverse.quiet = TRUE,
        repr.plot.width = 5,
        repr.plot.height = 3)

library(tidyverse)
library(plotly)

# Let's load up a familiar dataset: mtcars

head(mtcars)

p <- ggplot(mtcars, aes(x = wt, y = mpg)) +
geom_point() + 
geom_smooth() +
theme_bw() + 
labs(x='Weight (/1000 lbs)',
     y='Fuel efficiency (mpg)',
     title='Car Fuel efficiency by weight')

p

ggplotly(p)
