Refresh floating window

[dryodryo]

Thank you for a very helpful extension. I tried all of the available extensions and this is the only one that worked properly.

After opening the preview, I want to float the window. (Multi monitor setup.) Once the window is floating, the preview rendering disappears and I only get a blank window.

If I make a change in the code editor, this forces the floating window to refresh.

It seems that the WebView is recreated after detaching the preview window, and all its internal states are lost. I see two possible fixes:

• Ask Visual Studio Code to update its code so that the WebView states are preserved when attaching and detaching windows. This may be the best approach because it could also fix similar problems for all other extensions.
• Save the preview state in the extension’s state so that it is not destroyed along with the WebView. This requires some architectural changes in the extension and may incur some performance loss due to communication costs between the extension and the WebView.
