It’s not incorrect, it just jumped out to me when I read it. Similar to:
	- There is no data on the disk.
as opposed to:
	- There are no data on the disk.
"Data is” and “data are" are both technically correct so I guess this
one's more of a style choice than a typo.

The cross-referenced manual page (Isearch Yanking) doesn’t mention that
`isearch-yank-pop’ (27.2) can yank text when the previous command wasn’t
a yank. The only place it gets mentioned is in a comment in the source:

	;; Fall back on `isearch-yank-kill' for the benefits of people
	;; who are used to the old behavior of `M-y' in isearch mode. In
	;; future, this fallback may be changed if we ever change
	;; `yank-pop' to do something like the kill-ring-browser.

A separate function was made for the `kill-ring-browser’ functionality in 28.1
(isearch-yank-pop) but the old behaviour is still the default (isearch-yank-pop-only).
If that’s going to be the case long term, there should be a note of it in the manual.
Maybe something like:

	…usual ‘M-y’ (‘yank-pop’) command (see Yanking).  [However unlike the usual
	‘M-y’, ‘isearch-yank-pop’ will act like ‘C-y’ when the previous command wasn’t
	a yank. That is, it will yank the most recent kill.]  Clicking ‘mouse-2’ in the…

If the old `M-y’ behaviour WON’T be the default long term, then the FAQ should be
change to something along the lines of:

	[‘C-y’ and ‘M-y’ work the same in searches as they do in normal editing.]  See…

Thanks,
Ian
