Skins from the Super Mario Mash-up Pack once again disallows all forms of multiplayer, in same, seemingly suspicious way. This bug contradicts the hidden note from Different Minecraft Editions in Minecraft Help and makes players annoyed and confused when trying to toggle multiplayer, requiring them to switch away from the skin pack just to actually toggle multiplayer on or off.

Steps to reproduce:

1. With Minecraft open, go to Dressing Room
2. On the existing slot (that’s unused), click the hanger icon (Classic Skins button)
3. Equip a skin from the Super Mario Mash-up Pack
4. Return to main menu
5. Click Play
6. Click Create New
7. Click Create New World
8. Click Multiplayer and observe the toggles
9. Click Play

Expected result: On previous versions (that uses JSON UI), Switch-specific multiplayer could be toggled but cross-platform multiplayer should be locked disabled. The (offending) pop-up from the previous version would be "Platform-restricted skin".
Actual result: On step 8, Both cross-platform multiplayer and Switch-specific multiplayer over Nintendo Switch Online and Multiplayer toggle seem to be locked disabled, inconsistent to one from Minecraft Help. On step 9, an offending pop-up claimed that the skin isn't usable on (all forms of) multiplayer (see note) appears, contradicting one from Minecraft Help. However, as long as you didn't activate the resource pack of the Super Mario Mash-up Pack, this has no effect when entering the world as it basically only allows Switch-specific multiplayer over Nintendo Switch Online anyways.

Note: I was offended by the pop-up actually, based of "skin disallowed offending pop-up.JPG", the title of the pop-up translates to "Skin disallowed" and the description translates to "The skin you are currently using is from a content pack, that disallows multiplayer. Change your skin or continue (playing) the world on singleplayer (only)", the top button is "Continue without multiplayer", I wished the restriction and gete-keeping of the mash-up pack was abolished; The bottom one is "Change character / skin".
