In the new beta chat box position was defaulted back to thankfully, but it appears portal mode might still be defaulted to and not for new and most users which happened after recent updates.

Unfortunately I'm unable to test this currently as I already fixed this for myself some time ago but for a lot of people they were left confused when portal mode was on the old setting and not the new one.

Seeing as chat box setting was defaulted back to the most commonly used method in this beta, perhaps squeezing in the default change to the new setting for portal mode as well into this beta would be appreciated.
