drawingBufferWidth must be greater than zero.

Got this when trying to open a log in Firefox 106.0.5, Linux.

Uploaded the same log in Chrome and there weren't any errors. Then I reloaded the page in Firefox and tried again, and it worked without error.

```
An error occurred while rendering. Rendering has stopped.

DeveloperError: drawingBufferWidth must be greater than zero.

Reproduce the failure in Firefox 106.0.5 on Linux by opening the reported log, then inspect the rendering path corresponding to static/js/1.0bdc62d8b34eafc0234d.js and the drawingBufferWidth stack trace. Done means the log opens and renders in Firefox without the rendering-stopped error.
