Playground: Scrolling in text area randomly jumps back sometimes

[dbooth-boston]

When scrolling down through the JSON-LD Input text area (using my mouse scroll wheel), it sometimes jumps backward. This is actually quite annoying when one is looking for something in the window and it jumps around like that. The problem happens on both Firefox 100.0.2 (64-bit) and Chrome version 101.0.4951.64 (Official Build) (64-bit), Ubuntu 20.04.

Here is an example that illustrates the problem: https://tinyurl.com/2mj3943m In the top text area, if you watch its scroll bar while you scroll down, you will see that it jumps back sometimes. The problem actually occurs in both the upper and lower text areas.

Doesn't happen in Safari, but I verified it in Chrome.
