I get it straight from 'emacs -Q', so obviously the quantum
probabilities are different here 😀

Could be. The transient command log looks like this:

    e           ;; transient:emoji--command-Choose Emoji:👋🏾
    C-s         ;; isearch-repeat-forward
    C-x 8 e RET ;; isearch-emoji-by-name
    w           ;; self-insert-command
    a           ;; self-insert-command
    v           ;; self-insert-command
    i           ;; self-insert-command
    n           ;; self-insert-command
    g           ;; self-insert-command
    SPC         ;; minibuffer-complete-word
    h           ;; self-insert-command
    a           ;; self-insert-command
    n           ;; self-insert-command
    d           ;; self-insert-command
    RET         ;; minibuffer-complete-and-exit
    e           ;; isearch-printing-char

(should that really be calling `isearch-printing-char' at the end
there?)

'C-x 8 e RET' for the same emoji works fine.
