Thank you, Eli, for the most recent fix implemented in relation to #22637.
Both of the fixes that you have already implemented do indeed resolve the two
test cases.
You might be interested to know that the `window-scroll-functions` hook never
runs after `window-start` is corrected in the following example, so anyone
seeking to use that hook with a correct `window-start` is out of luck. In
addition to the test example below, this type of fact pattern occurs when using
things such as isearch and ispell (e.g., when programmatically moving to a
point that is not yet visible). Attached is an updated
`window_start_end_hook.diff` that depicts an example of how I have tentatively
dealt with it for the new hook (but I did not attempt to fix the WSF).
