Research direction

Reproduce the issue in VS Code Insiders on macOS by opening a Markdown file, selecting “Open as Preview,” and pressing CMD+W. Start by tracing the Markdown preview and window-close behavior; done means closing the file closes only the relevant editor and leaves the VS Code window and project open.

Description

Type: Bug

If I open any markdown file, and then click on the 'Open as Preview' icon button from the top right corner, it is closing the vscode window and my project when I close the file using CMD+W shortcut.
