CS1591 Warning occurring when making generated types `public`

Actual behavior

When setting "public": true in the NativeMethods.json file the compiler outputs warnings for missing XML Comments after building the application.

Types I am aware of right now (in my project):
ITaskbarList2.HrInit()
ITaskbarList2.AddTab(HWND)
ITaskbarList2.DeleteTab(HWND)
ITaskbarList2.ActivateTab(HWND)
ITaskbarList2.SetActiveAlt(HWND)
ITaskbarList3.HrInit()
ITaskbarList3.AddTab(HWND)
ITaskbarList3.DeleteTab(HWND)
ITaskbarList3.ActivateTab(HWND)
ITaskbarList3.SetActiveAlt(HWND)
ITaskbarList3.MarkFullscreenWindow(HWND, BOOL)

Expected behavior

No warnings and docs are generated accordingly.

Repro steps

1. NativeMethods.txt content:

// Debug purpose only
AllocConsole

// Taskbar progress bar
ITaskbarList3
TaskbarList
TBPFLAG

// Hide window from screenshot tools
SetWindowDisplayAffinity

// Clipboard operations
OpenClipboard
EmptyClipboard
GlobalAlloc
GLOBAL_ALLOC_FLAGS
CLIPBOARD_FORMAT
GlobalLock
GlobalFree
GlobalUnlock
SetClipboardData
CloseClipboard

2. NativeMethods.json content (if present):

{
  "$schema": "https://aka.ms/CsWin32.schema.json",
  "comInterop": {
    "useComSourceGenerators": true
  },
  "public": true
}

Context

• CsWin32 version: 0.3.265
• Win32Metadata version: 68.0.4-preview & 0.13.25-experimental
• Target Framework: net10.0

Start with the NativeMethods.json setting that makes generated types public and reproduce the CS1591 warnings using the NativeMethods.txt entries. Trace how the source generator emits the listed COM members, then verify that the build has no missing-XML-comment warnings and documentation is generated for the public types.
