Attributes of VFX Graph Nodes are missing space in the Node creation menu when attribute has two words and the first word is fully entered in the search

How to reproduce:
1. Create a new Unity project and install the Visual Effects package
2. Create any VFX Graph
3. In the Output block, open the Node creation menu
4. In the Search, start entering word "from" (e.g. enter "fro")
5. Observe the attributes "From Source"
6. In the Search, fully enter the word "from" and compare the results

Expected results: Both times attribute "From Source" has a space between words
Actual results: When the word "from" is fully entered, there are no space in the "From Source" attributes
