JSX: <svg : path /> parsed incorrectly

[strager]

See also a similar bug in TypeScript: microsoft/TypeScript#47219

esbuild rejects the following code:

import React from "react";
export function MyComponent() {
  return <svg : path />;
}

$ npx esbuild hello.jsx --bundle --external:react
✘ [ERROR] Expected ">" but found ":"

    hello.jsx:3:14:
      3 │   return <svg : path />;
        │               ^
        ╵               >

1 error

According to the JSX specification, whitespace is allowed around the : token.

Babel, ESLint, and Flow interpret this code correctly, treating svg:path as the tag's name.

esbuild does parse the following correctly (I think; I haven't fully tested):

import React from "react";
export function MyComponent() {
  return <svg:path />;
}

$ npx esbuild hello.jsx --bundle --external:react
[snip]
  // hello.jsx
  var import_react = __toESM(__require("react"));
  function MyComponent() {
    return /* @__PURE__ */ import_react.default.createElement("svg:path", null);
  }
})();
