How to reproduce (inconsistent):
1. Create and open a new project
2. Create and open in UI Builder a new UI Document
3. Add some element to the Hierarchy
4. Add any ScriptableObject from ObjectPicket to the “Data Source” attribute
5. Try doing these actions in random order:
- Add a property to “Data Source Path“
- Select the property and replace the string with a Space (then press Enter or save the changes)
- Save (CTRL+S)
- Undo (CTRL+Z) (using this usually helps a lot in reproduction)
- Change ScriptableObjects in “Data Source“
- Deselect and select the element (This usually triggers the corruption)

Expected result: Nothing breaks and nothing corrupts
Actual result: At some moment, the Attributes and Bindings section will fail to expand, and “IndexOutOfRangeException” errors will be thrown in the Console. Or, the UI Builder window will fail to update visual changes done to the UI Builder

Reproducible in: 2023.3.0a2, 6000.0.54f1, 6000.1.14f1, 6000.2.0b12, 6000.3.0a3
Could not test in: 2023.2.0a1 (No Binding section)

Reproduced on: Windows 11 Pro (24H2)
Not reproduced on: No other environment tested

Notes:
- The issue reproduction is inconsistent, but most of the time, when it reproduces, it will just momentarily corrupt the Bindings and Attributes sections of the UI Builder, until the window is reopened
- Only when the sections/UI Builder is corrupted, an “IndexOutOfRangeException“ error will be thrown in the Console
- The issue is easier to reproduce on 6000.2 and 6000.3 versions for some reason
- In version 2023.3.0a2, the editor crashes when the space is pressed after selecting the Data Source Path string
- Sometimes, if saved at the right time/after certain steps, the bug will corrupt the whole file. After reopening the UI Document, no element is visible in the Hierarchy, and no element can be added to the Hierarchy
