Option to *not* close file marked as viewed via keybinding

When you mark a file as viewed through the active editor menu bar or through a keybinding, the file will close. When you mark it as viewed through the tree view then it will not close. If a setting is needed I'll add one, but my hope is that this behavior is better for almost everyone.

Per this comment, it seems the default behavior for keybindings (or editor menu bar) calling pr.markFileAsViewed is to close the file, but for my workflow I'd prefer it didn't. Is it possible to add either a config setting, new command, or allow "args" in the keybinding to disable closing the active editor when this command is executed?

If it would be accepted, I could also attempt a PR for whichever of those options seems preferable. Thanks!

Edit: as a workaround (at least for keybindings) I found this seems to work okay - although the visual effect of closing and immediately reopening the editor is a bit jarring:

    {
        "key": "alt+j",
        "command": "runCommands",
        "args": {
            "commands": [
                "pr.markFileAsViewed",
                "workbench.action.reopenClosedEditor",
            ]
        },
        "when": "editorTextFocus && github:inReviewMode && isInDiffEditor",
    }

Empieza siguiendo el comando pr.markFileAsViewed desde sus puntos de entrada de asignación de teclas y de la barra de menús del editor activo, comparándolos con el comportamiento de la vista de árbol descrito en el issue. No se nombran archivos fuente ni pruebas; se considera completado cuando se proporcione una forma aceptada de invocar el comando sin cerrar el editor activo, preservando el comportamiento existente de forma predeterminada.
