Description
What happened?
chrome.printerProvider listeners (onGetPrintersRequested, onPrintRequested, onGetCapabilityRequested) register successfully in a Manifest V3 extension service worker but are never dispatched when the print dialog opens.
This is a regression from Edge 150.0.4078.65 — the last known working version. The issue persists through 151.0.4129.59.
