bug#60740: 29.0.60; Broken isearch-emoji-by-name

  *** New command 'isearch-emoji-by-name'.
  It is bound to 'C-x 8 e RET' during an incremental search.  The
  command accepts the Unicode name of an Emoji (for example, "smiling
  face" or "heart with arrow"), like 'C-x 8 e e', with minibuffer
  completion, and adds the Emoji into the search string.

These examples "smiling face" and "heart with arrow" work fine.

But typing e.g. 'C-s C-x 8 e RET waving hand RET' fails with:

  ⛔ Error (transient): Inconsistent transient state detected.
  This should never happen.
  Please open an issue and post the shown command log.
  This is a heisenbug, so any additional details might help.
  Thanks!
