bug#43717: [feature/native-comp] pdf-tools missing arrow tooltip

[Nicola Manca]

* General problem:

  I'm using auctex and pdf-tools for live preview. Between them it is
  possible to do direct and reverse text lookup: in pdf tools by
  C-<mouse 1> and in the latex source by C-c C-v. In the latter case, a
  red arrow is usually placed on the left side of the pdf document to
  highlight the line containing the text in the source. This arrow does
  not appear in the native-compiled branch.

* Related errors (from message buffer):

  pdf-util-tooltip-arrow: Invalid function: pdf-view-current-overlay

* Related .emacs config

  (setq TeX-view-program-selection '((output-pdf "PDF Tools"))
        TeX-view-program-list '(("PDF Tools" TeX-pdf-tools-sync-view))
        TeX-source-correlate-start-server t)
  (add-hook 'TeX-after-compilation-finished-functions
        #'TeX-revert-document-buffer)


* To reproduce

  - Install auctex and pdf-tools packages.
  - Create a latex document.
  - Compile it with sequential C-c until the generated pdf is opened in
    a window on the side of the source.
  - Try C-<mouse 1> on any text in the pdf and check if the cursor jumps
    in the corresponding position of the latex source.
  - Type C-c C-v in the source and check if the pdf view is updated.
  - If native-compiled the view is updated but the red arrow marking the
    position does not appear.
