Plugin is changing outputted code (not imports)

[gtjamesa]

Using 1.0.0-alpha.5. The import statements are being added as expected, but I noticed some code was also being altered. This happens when using the API example .swcrc and also when no rules are configured

...

// typescript source
public static postRaw(req: Request<RawRenderRequest>, res: Response) {
  const chartData = req.body?.chart;
  if (!req.body || !chartData || !chartData?.data.length) {
    //
  }
}

// swc build
static postRaw(req, res) {
  const chartData = req.body?.chart;
  if (!req.body || !chartData || !chartData?.data.length) {
    //
  }
}

// swc build + this plugin
static postRaw(req, res) {
  const chartData = this?.;
  if (!req.body || !chartData || !this.?) {
    //
  }
}

...

.swcrc:
