This doesn't repro on another package (newtonsoft) but confirming it repros on webview2.

Closing this github issue, however, as this seems to be coming from CPS (SynthesizedEmpty string is hardcoded into CPS tools). We should proceed with the feedback ticket for now, and see the results of CPS' investigation
