Bug report

After I added SWC loader, the mini CSS extract plugin could not be found. However, I added it. When I checked the relevant source code, I found that I judged whether there was a plug-in from this, not from this_ compiler. options. Do plugins perform judgment processing

Switching from SWC loader to TS loader is normal
