Bug: Pasted text loses org-indent-mode indentation when org-transclusion-mode is enabled

[YasserKa]

Summary

When both org-indent-mode and org-transclusion-mode are enabled in an Org
buffer, pasting text under a heading does not get the virtual indentation
(line-prefix/wrap-prefix text properties) that org-indent-mode normally
applies. The pasted text stays flush-left until any subsequent edit is made
to the buffer, at which point it snaps into correctly indented position.

Disabling org-transclusion-mode fully resolves the issue. The bug
reproduces with no active transclusions in the buffer. Simply having
org-transclusion-mode turned on is sufficient to trigger it.

Steps to reproduce

1. emacs -Q -l repro.el (see minimal init below)
2. Open/create an Org file with at least one heading and org-indent-mode
   active
3. Enable org-transclusion-mode in the buffer
4. Copy any line of text (M-w or select + M-w)
5. Paste it under the heading (C-y / M-x yank)

Expected: Pasted text is immediately displayed with the same virtual
indentation as other text under that heading.

Actual: Pasted text appears flush-left (column 0), with no
line-prefix/wrap-prefix property set. Typing any character anywhere in
the buffer afterward causes the pasted text to snap into the correct
indentation.

Minimal repro config

;; repro.el
(require 'package)
(package-initialize)
;; adjust to however you install packages
(unless (package-installed-p 'org-transclusion)
  (package-refresh-contents)
  (package-install 'org-transclusion))
 
(add-hook 'org-mode-hook #'org-indent-mode)
(add-hook 'org-mode-hook #'org-transclusion-mode)
