Further to that, it appears that (verify-visited-file-modtime (current-buffer)) is what causes the redisplay of the toolbar (and more).
I can manually cause a call to update_frame_tool_bar by evaluating this expression. I don’t have time to look further right now, but the call to Ffind_file_name_handler is a suspect. See also below.
file-name-handler-alist is a variable defined in ‘fileio.c’.
Its value is (("\\.gpg\\(~\\|\\.~[0-9]+~\\)?\\'" . epa-file-handler)
("\\(?:\\.dz\\|\\.txz\\|\\.xz\\|\\.lzma\\|\\.lz\\|\\.g?z\\|\\.\\(?:tgz\\|svgz\\|sifz\\)\\|\\.tbz2?\\|\\.bz2\\|\\.Z\\)\\(?:~\\|\\.~[-[:alnum:]:#@^._]+\\(?:~[[:digit:]]+\\)?~\\)?\\'" . jka-compr-handler)
("\\`/[^/]*\\'" . tramp-completion-file-name-handler)
("\\`/[^/|:][^/|]*:" . tramp-autoload-file-name-handler)
("\\`/:" . file-name-non-special))
