[Problem/Bug]: Saved PDF from print dialog option "Save as PDF" is deleted after WebView2 dispose

[rvoelkel-nest]

What happened?

When printing with Save as PDF option, saved PDF file is deleted, after app is closed with WebView2 component.

Happens in my app, in Outlook and also tested with WebView2WpfBrowser from WebView2Samples.

Was working with local installed WebView2 Runtime 105.0.1343.33, but not with current systemwide installed.

I find this happens when using the pre release SDK. But stable was ok. Although it stopped showing the small window at top right after print when you can launch from.

After update to WebView2 135.0.3179.73: open an image via Ctrl-Click in a new window. Choose 'Save image as' from context menu. The file dialog opens. Choose you destination folder and save. A temp file like c2b6a7fc-c5e4-43b7-95d5-43a921535095.tmp is created, but it never become your image file. After WebView dispose the temp file is deleted.

Thanks for reporting the issue. I could repro the issue with WPF samples. Opened internal bug to track this issue.
