Type params ScalaDoc for PartialFunction.compose incorrectly fused

[scabug]

The ScalaDoc for scala.PartialFunction.compose incorrectly limits the parameter type parameter for g to the same type parameter as itself.

Current: def compose[A](g: (A) ⇒ A): (A) ⇒ B |
Suggested Correction: def compose[C](g: (C) ⇒ A): (C) ⇒ B |

The parameter descriptions are also misleading.

tparam/param	description	note
A	the type to which function g can be applied	Instead of A a new name should be used
g	a function A => T1	Should be something similar to a function C => A

Still a bug in 2.13.0: https://www.scala-lang.org/api/current/scala/PartialFunction.html#compose[A](g:A=%3ET1):A=%3ER

Scala 3.6.3 gets it wrong in the same way.
