Weird line breaks in a chained but below column length codeblock

[CosmoMyzrailGorynych]

Input: (UI bindings from my reactive framework for Godot, condensed)

extends Node

func _ready() -> void:
	S.declare([
		S.bind_label(item_name, title),
		S.bind_label(item_description, description),
		S.bind_label(cost, cost_label),
		S.bind_label(buy_switch_text, buy_or_switch_label),
		S.bind_visible(active, self),
		S.bind_visible(should_show_cost, cost_container),
	]).bind(self)

Output:

extends Node


func _ready() -> void:
	S \
			.declare([
		S.bind_label(item_name, title),
		S.bind_label(item_description, description),
		S.bind_label(cost, cost_label),
		S.bind_label(buy_switch_text, buy_or_switch_label),
		S.bind_visible(active, self),
		S.bind_visible(should_show_cost, cost_container),
	]) \
			.bind(self)

While the code is still valid, it seems that it trips some check for the continuation lines? (double indents are very suspicious here)

Removing .bind(self) stops triggering this behavior.

Yeah it sees a chain of two functions that have to be output vertically, and wraps with trailing \ as it does with vertical chains of function calls. It doesn't understand that it's actually a special case where the function chain itself is "flat" and it's only the arguments in between that are/need to be broken (multiline). I'll have to think a bit about it. Thank you for the reports!
