Reproduction steps:
1. Create and open a new project
2. Create any new script (Assets > Create > MonoBehaviour Script)
3. Select that script from the Project Window
4. In the Inspector, in the Script preview try to select and copy some of the text

Expected result: The text gets selected and can be copied
Actual result: The whole text gets highlighted and then the preview turns blank

Reproducible with: 6000.2.0a4, 6000.2.0a5
Not reproducible with: 2022.3.59f1, 6000.0.40f1, 6000.1.0b8, 6000.2.0a3

Reproducible on: Windows 11, macOS 13 (M1)
Not reproducible on: No other environment tested

Notes:
- Reproduction can be inconsistent, but unselecting the Script and repeating 3-4th steps a few times should reproduce the issue
- On the 6000.0.0a4 version the issue reproduces while constantly selecting text with CTRL+C and CTRL+V, while in the pre-FAV version (6000.0.0a3) the issue does not reproduce, but the text gets randomly rearranged instead
