Prerequisites: CSS positioningReact component basics
Newbie friendliness: 50
Research direction: The bug is a CSS issue where the time dropdown in the /remind command expands the modal instead of overlaying it. Look for the dropdown component in the reminder modal (likely in mattermost webapp). The existing comments may contain hints. Since the issue is assigned, check if the assignee is actively working or has left feedback. To fix, adjust the dropdown's CSS to use absolute positioning and a higher z index so it appears on top without expanding the parent.
