This bug (and a similar bug#37526) are already fixed in what will
become Emacs 27, we just forgot to close them.  Closing now.

Thanks.

[Message part 3 (message/rfc822, inline)]

In Calc enter:
90 <RET> S <f3> I S <f4>
S <f4>
The first key sequence gives 90 again.
The second key sequence shows 1, however expected is 90 as well.

Looking at the recorded macro with C-x C-k e <RET> shows this:
Command: last-kbd-macro
Key: none

Macro:

ISS            ;; self-insert-command * 3



<view-lossage> shows this:
 C-x * [calc-dispatch]
 * * 9 [calcDigit-start]
 0 [calcDigit-key]
 <return> [calcDigit-nondigit]
 S [calc-sin]
 <f3> [kmacro-start-macro-or-insert-counter]
 I [calc-inverse]
 S [calc-fancy-prefix-other-key]
 S [calc-sin]
 <f4> [kmacro-end-or-call-macro]
 S [calc-sin]
 <f4> [kmacro-end-or-call-macro]

It looks like the one key press of 'S' was seen twice (as
[calc-fancy-prefix-other-key]
and as [calc-sin]) and also recorded twice in the keyboard macro.
Using the macro thereafter leads to a wrong result.
