Please provide a preview handler that first displays the thumbnail of the file, and if no thumbnail is available, shows the file icon. Refer to commit [bfb9f9d2af7d9325] as a Delphi reference.

Sorry, wrong reference. It should be ShellItemImage.pas in commit f564ad32da (referenced from ticket [322eaf262fbcb674]).

Starting implementation for thumbnail/icon preview handler.

Implemented in 996809760d. Added manual uiltin.thumbicon handler that shows shell thumbnails with icon fallback, with tests and README update. Branch: tb6914810-thumbicon-handler.

Fix was incomplete. New handler does not show up in the configuration lists, and never activates. Adding missing file fixed the problem.
