The updateSettings function is not changing layout type to the mobile view in the embedded report

I have an embedded report (that already have mobile layout) that I'm trying to change the visualization from default layout to the mobile layout using the updateSettings function like the example below:

const newSettings = {
    layoutType: models.LayoutType.MobileLandscape
};

report.updateSettings(newSettings);

When I do it after the report being loaded, the report doesn't change the layout.

I'm only able to show the mobile layout when I set the right layoutType when I'm embedding the report. But in the documentation page, it says that we can change the layout type after we load the report.

Is it an error in the javascript SDK or is it expected behaviour?
