Thanks go to Lawrence for making me find a clipboard analyzer on Windows.
Tto my knowledge, in decades on these ngs, nobody ever has discussed them.

This is the one I used:'
  InsideClipboard v1.30
  Web site: https://www.nirsoft.net

For those in this thread who are not on Windows, there are certain
Windows-specific oddities that may need to be explained in that output.

The "format" field is a numeric identifier that Windows uses internally to
label a clipboard format.
 Format ID 1      = CF_TEXT
 Format ID 7      = CF_OEMTEXT
 Format ID 13     = CF_UNICODETEXT
 Format ID 16     = CF_LOCALE
These are built in Windows formats.
They exist on every Windows system.

Yet the important ones in this test were:
 Format ID 49426  = HTML Format
 Format ID 49661  = Chromium internal source RFH token
 Format ID 49683  = Chromium internal source URL

For each of those, Chromium told Windows (taking one as an example):
  "I want to register a clipboard format named HTML Format"
   and Windows assigned it ID 49426.

Windows doesn't care what it's called.
Windows just assigns it an available number.

Why are the second set of numbers so big?
Because Windows built-in formats use up all the small numbers:
  1, 7, 13, 16, etc.
While application-registered formats use available large numbers:
 49426, 49661, 49683.

These indicate that Chromium placed multiple formats on the clipboard
 HTML Format
 Chromium internal source RFH token
 Chromium internal source URL

But when your Notepad++ macro rewrote the clipboard, all of those formats
disappeared. 
 A. This is why Ctrl+A started working again.
 B. The shortcuts.xml CTRL+B macro removed the HTML Fragment land mine

This proves the PSA (at least the problematic Chromium portion of the PSA).
And it proves the single-step solution (on Windows).

Voila!
I love one-step automation!
