How to reproduce:
1. Open any project with UI Builder Installed
2. Create a "UI Document" and open it
3. Create a "Button" element and increase the "Text size"
4. Double-click the "Button" to start typing and type continuously
5. Or press "Enter" in the "Text" field in the Buttons inspector and start typing continuously

Actual result: Characters typed at the end of the line can be hardly seen, typing and checking your last character inputted is difficult, this is especially visible when typing the last character of a second paragraph
Expected result: When typing, the last character entered is always visible, as is in other parts of Unity
