Azir's Sun Disk procs Yasuo Shield (GAMEPLAY)

Playing against an Azir I noticed that whenever I was max flow and he had his sun disk conjured, it proc'd my shield instead of directly negating my health.

• Situation: Have Azir on blue side with Disk of the Sun conjured.
• 2. Have Yasuo with full flow.
• 3. Have him attract turret agro and take a shot.

This might be a minor bug, or my eyes lying to me.
