[BUG Report] A incorrect behavior of the shell variable $RANDOM

Zsh Version: zsh 5.8.1 (x86_64-ubuntu-linux-gnu)
Operating System: Ubuntu 22.04.1 LTS running in Hyper-V

Description: $RANDOM is always the same value when I try to use it in “$()” expression.
       For example:
       [cid:image003.png@01D922CB.7B4D0190]
       Another one:
       [cid:image005.png@01D922CB.7B4D0190]
       And the same problem happened when I used the zsh built from the latest source pack from sourceforge. So is it a real bug or a feature I don’t know?

This is working as intended. From `man zshparam`:

> subshells that reference RANDOM will result in identical pseudo-random values unless the value of RANDOM is referenced or seeded in the parent shell in between subshell invocations.
