On Brave v1.70.126 with W11, when restoring a group all of the tabs in that group automatically un-discard simultaneously, which can lead to rate limiting (503) errors on many websites if you have enough tabs from the same website open in that group. (as far as I'm aware, this is a fundamental issue with how chrome/chromium tries to restore tab groups. By default it seems to restore them all at once, which leads to rate limiting issues) If there was an option to keep tabs discarded upon restoring the group however then (I think) that would prevent this from being an issue unless you manually tried to un-suspend all of the tabs at once.
