Folder name not rendered fully if there is a dot/period (.) character in the name

Steps to reproduce:
1. Open new project
2. Create new folder with name that has a `.` (period) character in it. For example "5. Test"
3. Observe the folder showing up as "5 " in the Assets window. When you click on it, it still shows the actual folder name at the bottom of the window

Expected: Folder name should be shown in full
Actual: The last dot in the name will eat up whatever was written after it

For example: "Test.Test" becomes "Test"
"Test..Test" becomes "Test." and so on.
