What's the problem? Describe what went wrong.

The shadow will not render (or z-fighting in the case of OpenGL) when not using fast depth. Fast depth is enabled by default for this game and is thus marked as solved on the wiki but I don't think that is a solution.
This issue is comparable to the subtitle issue in SpongeBob SquarePants: Revenge of the Flying Dutchman: https://wiki.dolphin-emu.org/index.php?title=SpongeBob_SquarePants:_Revenge_of_the_Flying_Dutchman

In both cases Fast depth is correct while 'normal depth' is not.

What steps will reproduce the problem?

Play the game.

Is the issue present in the latest development version? For future reference, please also write down the version number of the latest development version.

Yes, present in 5.0

If your issue is a graphical issue, please attach screenshots and record a three frame fifolog of the issue if possible. Screenshots showing what it is supposed to look like from either console or older builds of Dolphin will help too. For more information on how to use the fifoplayer, please check here: https://wiki.dolphin-emu.org/index.php?title=FifoPlayer

See wiki.

Is there anything else that can help developers narrow down the issue? (e.g. logs, screenshots,
configuration files, savefiles, savestates)

With https://github.com/dolphin-emu/dolphin/pull/8244 Vulkan renders like OpenGL, a z-fighting shadow.
