Incorrect syntax highlighting of inline function body within the argument list of a function call

Tested versions

v4.2.2.stable.official [15073af]

System information

Windows 10

Issue description

When an inline function definition within another function's argument list contains an inline if statement, the syntax highlighting of the statement following the inline if is incorrectly applied.

In this screenshot, the final my_var is colored with the color used by types in an argument list. Presumably because the statement comes after the colon : character of the if, which is the same way a type would be specified in an argument list.

Steps to reproduce

func test():
	var my_var = true
	tree_entered.connect(func(): if my_var: my_var = false)

Is fixed in the latest Godot-4-3-dev-6, probably by #86176.
