Error when using method notation (->) on multiple lines

[lifepillar]

Edit: use a much simpler example.

Steps to reproduce

1. Create lib.vim with the following content:

vim9script

export def Noop(n: number): number
  return n
enddef

2. Source the following script:

vim9script

import "./lib.vim" as lib

const x = 1

var result = lib.Noop(x)->lib.Noop()->lib.Noop()  # OK

result = lib.Noop(x)
          ->lib.Noop()->lib.Noop()  # OK

result = lib.Noop(x)
      ->lib.Noop()
      ->lib.Noop()  # ERROR

Result:

E1013: Argument 1: type mismatch, expected number but got func(number): number

Expected behaviour

The script should execute without errors, as per :help vim9-line-continuation:

For a method call using "->" and a member using a dot, a line break is allowed before it

This also fails:

result = lib.Noop(x)->lib.Noop()
	->lib.Noop()
