P: add support for displaying HDR photos in Grids on Adobe Portfolio (myportfolio.com sites)

The extensive HDR support across all versions of Lightroom is amazing. However, sharing the images is still challenging and it would be incredibly helpful if Adobe Portfolio supported HDR photos (ideally shared as gain maps).

The existing HDR support in LR Web Galleries is great (example). However, it lacks the capabilities many photographers are seeking to share their work. Adobe Portfolio is a much better fit for many people, especially given it's included with Creative Cloud and the excellent Lightroom integration.
