Site with ServiceWorker not working in CEF

[rado]

I cannot get running one site working in CEF in the cefclient from cef_binary_120.1.10+g3ce3184+chromium-120.0.6099.129_windows32 - in console and log it shows error like

Code: Select all

[1228/103039.590:INFO:CONSOLE(1)] "Uncaught (in promise) TypeError: Failed to read the 'ready' property from 'ServiceWorkerContainer': Illegal invocation"

I've also tried chromium runtime with the same result. Site works in Chrome and Edge. Site URL is https://vavada.com/
Any idea what could be wrong or how to workaround this? I've tried to set navigator.serviceWorker to undefined in the OnContextCreated(), but it seems the browser restores it anyway. Is there better way how to disable service workers? Maybe this site would work without them. Thank you.
