Context

In or around the release of deno 2.2 the JSX warnings for unsupported-jsx-tsx were removed, suggesting the ability to cleanly publish JSX components from within a .tsx file of a package publishing into JSR.

The sample repo shows an error when importing into a Deno + Vite application, a JSR published module that exports a React/JSX component from a .tsx file, with no special 3rd part bundling or transpliation. Just what Deno/JSR prepares as it publishes the module.

@lucacasonato suggested this may be an issue with the "NPM tarball transpile [maybe] not working correctly for TSX."
