insert option + chunks places ___$insertStyle function in every chunked file

[mcshaz]

When rollup is run with

   output: { fomat: 'esm',
      ...
   plugins: [rollupPluginSass({insert:true}), ...

multiple chunks (which don't import any css) have the insert css function ___$insertStyle needlessly placed at the top of each chunked file.

ideally this function to insert a style element into the header would be added earlier in the rollup build pipeline so that it could be chunked to a single, appropriate file.

Edit

After having created this issue I saw there have been no commits to this repository for 13 months (at the time of writing). if anyone is a bit stuck on this issue, I moved to rollup-plugin-postcss which works as expected (only placing the insert css function once in the bundle of outputs).
