JS dialogs default impl doesn't work in alloy runtime style

[Czarek]

Is it supposed to work by default? From OnJSDialog docs it seems it should work:

Code: Select all

Set |suppress_message| to false and return false to use the default implementation


But it doesn't work for me.

OS: Windows 10.
CEF version: 130.1.15+g34b05bb+chromium-130.0.6723.92

Just tested with cefclient with alloy style:

Code: Select all

cefclient.exe --use-alloy-style


And JS dialogs don't work.

With chrome style JS dialogs also don't work:

Code: Select all

cefclient.exe --use-chrome-style-window

This is craaaazy. Sometimes JS dialogs work and other times they do not. I am talking about alert/confirm/prompt.

Another strange thing is that sometimes when it doesn't work I launch another instance of cefclient and then the js alert appears at that exact moment in the previous app. Only after launching another instance of app.

In "cefclient > Other tests > Dialogs" when js dialogs don't work I reload the page, confirm leaving the page. And after that I press "Show confirm" button and dialog doesn't appear, but I see that "console.log" file adds this warning:

Code: Select all

Level: Warn

Message: A window.confirm() dialog generated by this page was suppressed because this page is not the active tab of the front window. Please make sure your dialogs are triggered by user interactions to avoid this situation. https://www.chromestatus.com/feature/5140698722467840

It starts adding these warnings when pressing only after I reloaded page. Alert/confirm/prompt don't work at all while testing that session even before reload.
