In Tosfot Shabbat 39b, they cite Harav Rabenu Yonah:
וה"ר יונה מפרש בטלה אפי' בקדירה חייתא והיינו דקאמר בטלה משמע לגמרי מכל דבר:
He is not in the list of Baale Tosfot in Wikipedia. He also seems to not be mentioned in Shem Hagedolim. I don't think it's the Rabenu Yonah Girondi who is from Chachme Sfarad. Who is this Rabenu Yonah?
