React CodeSnippet doesn't update right overflow indicator on resize

Detailed description

It's possible to get the CodeSnippet component into a "wrong" state by scrolling it to the very right (making the right overflow indicator disappear), and then resizing the snippet (e.g. by resizing the browser window) so that the snippet isn't fully scrolled to the right anymore. The indicator should appear again, and I think there is even code in there that should make this work, but it doesn't.

Steps to reproduce the issue

1. Open the Code Snippet singleline
2. Scroll the snippet to the very right, making the indicator disappear
3. Resize the browser window so the snippet gets smaller, e.g. by increasing the size of the dev tools
4. See that the indicator doesn't reappear
