bug#48310: 28.0.50; Cannot list the list group |

I cannot repeat this in emacs -Q, this takes place in my running Emacs
session:
I do:
C-h f list
and inside I go with cursor to the hyperlinked `list` followed by the
word "group". I press enter, and I get this:
(lax-plist-put plist prop val)
Change value in PLIST of PROP to VAL, comparing with ‘equal’.
(setq plist (plist-put plist "d" 4))
(plist-member plist prop)
Return non-nil if PLIST has the property PROP.
(plist-member '(a 1 b 2 c 3) 'b)
⇒ (b 2 c 3)
Data About Lists
(length sequence)
Return the length of vector, list or string SEQUENCE.
(length '(a b c))
⇒ 3
(length<)
----------- HERE IS WHERE LISTING STOPS WITH ERROR:
