Request Body input not typing properly

[jessicaaawu]

Describe the bug
In Graph Explorer, the "Request Body" input field does not allow normal typing behavior. Users are only able to type one character at a time—after each keystroke, they must re-click into the field to type the next letter. However, pasting works as expected. This significantly disrupts the editing experience.

To Reproduce
Steps to reproduce the behavior:

1. Open Graph Explorer.
2. Select a method that uses a request body, e.g., POST.
3. Click into the "Request Body" text area.
4. Attempt to type a sentence normally.
5. Notice that only the first letter appears, and the focus is lost after each keystroke.

Expected behavior
Users should be able to continuously type into the Request Body input without losing focus after each character. It should behave like a standard text area.

Additional context
We need to fix this bug before Build as we will get more traffic, especially with new APIs being announced.
