Missing space in 'Unknown element name' error

The codec error produced for a string identifiable or many similar string-keyed objects misses a space, which is inconsistent with other errors.

To reproduce

1. Run the following command:

/give @s diamond_sword[consumable={animation:tater}]

2. Observe that the error produced is Malformed 'minecraft:consumable' component: 'Unknown element name:tater' instead of the expected Malformed 'minecraft:consumable' component: 'Unknown element name: tater'
