I think your point about ensuring that the presentation of objects in
the accessibility tree does not confuse users into thinking that they
have interactivity options they don't have is an important one. Users
have expectations about what you can do with an image node in an
accessibility tree.

Having said that:

1. On the one hand, why can't we distinguish between ordinary images
and video posters in the accessibility tree to reflect any differing
available functionality?

2. On the other, why shouldn't a UA offer the ability functionality
specific to poster images, such as a "Open poster image in New Tab"
context menu item? I think UAs are free to do what they want here.
