When you are searching through the creative mode inventory search bar (in the tab with the compass on the top right) while a status effect ends, the inventory moves to the center of the screen, but the text you just entered stays slightly right.

Steps to Reproduce:

Give yourself any status effect for 10 seconds (200 seconds for instant damage and instant health)
Before the status effect ends, open the creative mode inventory search tab and enter some text into the search bar
Wait for the status effect to end
When it ends, you should see the text show outside of the bar.
