@mjbvz do you have any ideas?

Yes, we destroy the html preview whenever the user switches away from it. This is by design.

The proper approach is write the html preview so that it can save its state and then recreate itself from this state. I believe the state needs to be saved by the extension code itself. Setting cookies in the webview doesn't work and I don't think local storage will either, but I'd have to check this.

For an example of this, take a look at the markdown extension: https://github.com/Microsoft/vscode/blob/master/extensions/markdown/media/main.js It doesn't really persist any state but it does set the initial view position using vscode-markdown-preview-data and it sends data back to vscode using window.parent.postMessage

The problem here that our HTML Preview is a complex Web application which depends on the backend server. We need 1-2 secs to establish a connection.

2-nd problem, we don't render HTML content on-the-fly as Markdown does. Yes, in your case you can control these things. We have a pre-built Web application based on Rect components. That is a very expensive operation for us to "refresh" application.

Finally, if we have active session between Web-previewed APP and our backend (for example, physical USB Serial Monitor), we can't keep this session when a user switches between tabs.

In any case, thanks a lot for the info.
