GoToR link opens target PDF but always jumps to top — how to open at exact position?

[BaigMirzaTouqir]

I'm implementing cross-PDF linking with PyMuPDF (fitz) for an automation pipeline where one PDF needs to open another PDF at a specific bookmark location.

The link works — it opens the correct file — but the viewer (e.g., Adobe Acrobat) always scrolls to the top of the target page, not to the precise bookmark coordinates.

Here’s the relevant code snippet:

import fitz

link_details = {
    "kind": fitz.LINK_GOTOR,
    "file": relative_link,       # relative path from source to target
    "page": adjusted_page_no,    # 0-based index of target page
    "to": target_point,          # bookmark rect value (x, y)
    "zoom": 0,
    "from": inst_rect            # clickable rectangle in source PDF
}

source_page.insert_link(link_details)

This is technically impossible - PDF specification restriction, not a PyMuPDF one.
