WinForms - Opening file picker via <input type="file"> does not correctly restores focus after canceling/picking a file about cefsharp HOT 5 OPEN

Issue exists since v102.0.90, the last version this works correctly is 101.0.180

Likely the result of this upstream change. CEF switched to using Chromium dialogs.

I see. I wonder, how come I cant just work around this and do browser.Focus() on the Form.Activated event (which is correctly triggered when file browser is closed)? Why does the Focus() return false? Or even when it does returns true, it still does not focus on the browser control. What would be the proper way to focus on the browser manually?

You'd have to debug to find that out.

browser.GetBrowserHost().SetFocus(true);

Seems like there are multiple issues regarding that change. We have a DownloadHandler implemented, where we are specifying the download path manually and it is being ignored - the last path is always used for the dialog.

var fileName = downloadItem.SuggestedFileName;
var pathToDownload = Path.Combine(path, fileName); 
callback.Continue(pathToDownload, showDialog: true); // no matter what the value of pathToDownload is, the dialog always points to last used download path

You can show your own custom dialog for downloading files and you should be able to do the same for the file picker as well.
