The blinking cursor in elm_code is on top of the main menu submenu when opened over a cursor. This is present in ecrire and also edi. The following screenshot does not do it justice but does show how to replicate. It is not as noticeable in edi as the submenu's background is transparent. But the cursor blinks on top of the icons and text. Just open a submenu over the cursor in edi or any elm_code with main menu.
