 ### Fixed
 - Fix `mpl_to_plotly` not setting `paper_bgcolor` and `plot_bgcolor` from the matplotlib figure and axes backgrounds, so converted figures match the source figure's background colors [[#5285](https://github.com/plotly/plotly.py/pull/5285)], with thanks to @robertoffmoura for the contribution!
+- Fix rendering issue causing a too-large div when calling `Figure.show()` in Google Colab [[#5718](https://github.com/plotly/plotly.py/pull/5718)]
