Implicit inlay hints only show the first implicit call of a chain

[francesconero]

Describe the bug

//> using scala 2.13.15

implicit def aString: String = "a"
implicit def lengthOfString(implicit s: String): Int = s.length
implicit def toLong(implicit i: Int): Long = i.toLong

def toDouble(implicit l: Long): Double = l.toDouble

toDouble // the inlay hint only shows (toLong) but I expected it to show (toLong(lengthOfString(aString)))

Expected behavior

Implicit inlay hint should show (toLong(lengthOfString(aString))) for the toDouble call but only shows toLong

Thanks for reporting! I can reproduce, must be regression connected to the change to compiler backed ones.
