Instant preview misplacement with tabs above #6735
Description
Context
Reported here first: #6704 (comment).
Bug description
Instant previews enabled globally with navigation.instant.preview.
When there are tabs above a previewable link, the preview windows can be misplaced: it seems the preview windows position are calculated once, when the page loads. If I change tabs above previewable links, and these tabs have different heights, then all previewable links after these tabs have misplaced preview windows. If I reload the page, staying on the second tab, positions are recalculated correctly. Well, these are assumptions, you'll know better what's really happening 🙂

Steps to reproduce
- Serve the given reproduction and go to the home page.
- Assert both previewable links have correct preview window positions.
- Now change to second tab in the "Tabs before" section.
- Assert that first link preview is still correct, but second link preview isn't. Increase or reduce space below second link (by scrolling) to see both behaviors (when there's enough space below the link to show the preview window, or not).
