Nested previews are only partially visible

[Stvad]

If I preview link inside another preview, the internal preview is only partially visible.
This is because the outer preview box is in iframe and constraining what can potentially be visible.

Not entirely sure how to solve this so far. Ideally all tippy instances (even nested ones) would share the same shadow-root-container but that seems impossible with cross origin iframes

Other option is doing something like - internal click only send a signal to a parent, which actually does previews, but that'd require some rearchitecture

Also, it seems that nested previews don't work for fragment links because mutation observer doesn't get at the shadow root content
