@react-pdf/png-js redefines Buffer?

[cefn]

Attempting to migrate a project to pnpm and vite which successfully used @react-pdf/renderer a year ago. You can see the stable version using npm and nextjs at https://cefn.com/cv

I had to upgrade to 3.0.0 owing to issues in version 2 like this one and this one

However, now an attempt to run tsc && vite build leads to the following fatal error - both lines are source code which I believe comes through dependencies from @react-pdf/renderer@3.0.0

This may have been an artefact of the module patching attempted in https://www.npmjs.com/package/vite-plugin-shim-react-pdf and which was no longer needed, but had affected my locally-versioned module.
