A button, with no icon or label, renders at the bottom of the activity list.

Start with the attached screenshot and reproduction recording to identify the activity-list button and its context. Review the logs attached through PR #10863 for related evidence, then trace the corresponding desktop UI entry point. Done means the button has a visible label or icon and the activity list no longer renders an unidentified button.
