> 1. Open any buffer where you can input text (e.g. `fundamental-mode')

> The selected menu item is chosen/accepted.

> IF you're using the transient.el bundled with Emacs 30.1 (0.7.2.2): You

> 
> IF you're using the newest transient.el from ELPA (0.8.5 at the time of
> writing): The error "BUG: Cannot determine suffix object" is raised
> after selecting the menu item. Hitting C-x 8 e e again will raise the

Thanks.  Jonas, can you please look into this?
