Can't edit the memo attached to alias e-mail addresses because of greyed out "Save" button

Since the UI change, on the email aliases section, for the '@mailbox.org' aliases (Not custom domain aliases, though I don't know if this issue shows up there also) the "Save" button on the Memo part of each email alias is greyed out. This means you can't save any changes you make to the Alias addresses' memo. The button remains greyed out even if you edit the actual memo text box too. I can see there are some other issues reported with Greyed out buttons in the forums as well. Please fix.
