pluginData memory leak

[TomokiMiyauci]

When pluginData was specified, memory usage increased with each rebuild.

main.mjs

import { context } from "esbuild";

const namespace = "testing";

const ctx = await context({
   stdin: {
    contents: `import "testing";`,
  },
  plugins: [
    {
      name: "testing",
      setup(build) {
        build.onResolve({ filter: /^testing$/ }, () => {
          return { path: "testing", namespace, pluginData: { value: "test" } };
        });

        build.onLoad({ filter: /.*/, namespace }, (args) => {
          return { contents: "console.log(0);" };
        });
      },
    },
  ],
  write: false,
  format: "esm",
  bundle: true,
});

setInterval(async () => {
  await ctx.rebuild();
}, 100);

If you run this, you will observe the Object usage increasing over time.

node --inspect main.mjs
