Commander doesn't clear perpetual effects when returning to command zone

[Dish1596]

Describe the bug
AI doesn't clear negative perpetual effects from their commander. Not sure if players have the option to do so.

To Reproduce

1. Have AI put their commander on the battlefield.
2. Cast a card such as Patriar's Humiliation that applies a negative effect to the AI's commander.

Expected behavior
MTGA patch notes from 2022.16.0 say
"Brawl Commanders & Perpetual Effects

• We are adjusting the rules around Brawl Commanders and Perpetual to make the two mechanics play better together
• As you move your commander to the command zone, you may choose to remove all perpetual effects on that Commander
• That this is all or nothing choice; you cannot pick and choose effects to keep"

(https://mtgarena-support.wizards.com/hc/en-us/articles/6712732957716-Patch-Notes-2022-16-0)

The AI should choose to do this if something like Patriar's Humiliation was cast on their commander (having a commander with no rules text is pretty bad!). Players should have the option to do this, too (though I haven't tested if they have that choice).

Screenshots
Julia's commander no longer has rules, thanks to Patriar's Humiliation.

Once an object changes zones, the timestamp of the perpetual effect changes to, effectively, "negative infinity". That is, earlier than any other non-perpetual timestamp.
