[Problem/Bug]: SharedWorker stops to work after page reload until DevTools attached #4852

Open sorokinva opened 1 month ago

What happened?

Im using webView2 to display spa which uses SharedWorker for background work. It works good, but if you reload page (right click - refresh) shared worker stops to work until you attach devtools to it, after that refresh works until devtools detached. If I have two webView2s attached to same shared worker refresh works, probably because its being kept alive by another instance. I suspect it might be something about cdp, playwrite and cypress had similar issues https://github.com/cypress-io/cypress/pull/28254 https://github.com/microsoft/playwright/pull/18976

Do you know if it was working in 128? Which last version you have seen it working?

@vbryh-msft Hi, sorry for the delay, thanks for response. I checked it on 128.0.2739.79, it still reproduces. Im not sure we ever saw it worked, it was just raised during internal dev session.
