Starting macOS 15/iOS 18 TextKit 2 extra line frame is more broken (height always been broken) than previously. The same code return different values when run on macOS 14/iOS 17 and macOS 15/iOS 18.

The problem is that extra line fragment (NSTextLineFragment) origin and size is incorrect. I sketch the problem with the code snippet below:

// Storage
let textContentManager = NSTextContentStorage()

// Layout

	set _doc to document of window 1
	if _doc is not missing value then
	-- front window is a document window
	set _title to _doc's name
	set _blog to _doc's current blog's name
	set _tags to _doc's tags
