Discrepancy in signature of `Tuple.splitAt` between api website and implementation

[Sporarum]

(Also on 3.2.0) https://dotty.epfl.ch/api/scala/Tuple.html# Displays:

inline def splitAt[This >: Tuple <: Tuple](n: Int): (This, Int)

Whereas the signature in the implementation is:

inline def splitAt[This >: this.type <: Tuple](n: Int): Split[This, n.type]
