[kbkpbot]

Describe the bug

As the code shown

This is extract from issue #23916

Reproduction Steps

m.v

module main

fn second[K,V](x map[K]V) {
	println('second: x.typename = ${typeof(x).name}')
}

fn first[T]() {
	x := T{}
	println('first: x.typename = ${typeof(x).name}')
	second(x)
}

fn main() {
	first[map[string]string]()
	first[map[string]int]()
	first[map[string]u8]()
	first[map[string]rune]()
}

Expected Behavior

first: x.typename = map[string]string
second: x.typename = map[string]string
first: x.typename = map[string]int
second: x.typename = map[string]int
first: x.typename = map[string]u8
second: x.typename = map[string]u8
first: x.typename = map[string]rune
second: x.typename = map[string]rune

Current Behavior

first: x.typename = map[string]string
second: x.typename = map[string]rune
first: x.typename = map[string]int
second: x.typename = map[string]rune
first: x.typename = map[string]u8
second: x.typename = map[string]rune
first: x.typename = map[string]rune
second: x.typename = map[string]rune
