The bug
Text on item tooltips now apply a line break if the string surpasses a certain length, which wasn’t the case in 26.3. This causes items with long names or even ids to apply a line break after a certain character length, as well as line breaks on items with custom text.
How to reproduce
Go to the creative inventory.
Search for a splash potion of the turtle master.
Hover over it.
Expected result
The item name would not contain line breaks.
Observed result
The item name now contains a line break.
