Panel application on home page not re-sizing for mobile

The application does not resize to the mobile screen size. This means users have difficulties understanding that this is an interactive application.

When I look at https://panel-gallery-dev.holoviz.dsp.anaconda.com/portfolio_analyzer or the other apps on my phone they indeed don't look so great.

If I run Lighthouse or PageSpeed

It complains about this:

Does not have a tag with width or initial-scaleNo <meta name="viewport"> tag found

Does this make sense for Panel apps to set this? Or could it make things worse?
