We’ve just deployed a new release that uses the new [Resize Observer specification](https://wicg.github.io/ResizeObserver/) where available (which unfortunately is just Chrome for now according to [Can I use](https://caniuse.com/#feat=resizeobserver)). Resize Observers make Observable much more robust in detecting when cells resize asynchronously.

Alternatively, you can dispatch an _update_ event to tell Observable explicitly that a cell has resized as shown in the [Introduction to HTML](https://beta.observablehq.com/@mbostock/introduction-to-html) notebook.
