Server REST console not showing all options on narrow screens

There is a JavaScript REST console in the left bottom corner on REST landing page (default on http://localhost:8080).

After clicking the "[+]" button, the console expands to 50% of the screen. However, sometimes it's not enough to show all the provided options, for instance on my monitor (23" 1920x1080) I don't see (and therefor cannot use) the TTL and Max-Idle options.
