Preserving of text properties

Hi, the manual claims ,----[ info://lispref/Text+Properties ] | Copying text between strings and buffers preserves the properties | along with the characters; this includes such diverse functions as | `substring', `insert', and `buffer-substring'. `---- but if I try that I observe that (at least for me) weird behaviour. Suppose I have an buffer in lisp-interaction-mode and font-lock-mode (scratch). There is the defun (defun foo () "Some doc string with a variable `var'" (while foo bar)) from point 727 to 801. So if I do (insert (buffer-substring 727 801 "*scratch*")) in a buffer without font-lock active (fundamental mode) the text properties should be preserved. But all text properties get stripped except these for the »`var'«. The difference is if you do a `list-text-properties-at' that »`var'« has a list as face property `list-text-properties-at' in scratch for »`var'» ,---- | Text properties at 778: | | font-lock t | face (font-lock-reference-face font-lock-doc-string-face) `---- All the other elements have a single element as the property face. Is there an error in the manual in my understanding (most sure) of it or in the preservation of text properties.
