Request body only allows you to type one character at a time

[ElinorW]

Describe the bug
I've noticed a bug where users cannot type properly in the Request body. You can only type 1 letter at a time, you need to re-click into the window to type another letter. You can paste things in properly, but users should be able to type properly into the Request body section

To Reproduce
Steps to reproduce the behavior:

1. Go to Graph Explorer
2. Type on request body editor

Expected behavior
users should be able to type properly into the Request body section

I can confirm that this issue is not browser specific. I've been able to repro on Chromium and Gecko browsers.
