When editing the maximum mark of a question in a quiz, the edit box is not tall enough to display the numbers. I tested on the Mt. Orange demo, Sandbox demo, and the Moodle QA site. I tested in Chrome and Firefox. The box is usually a little bigger in Chrome and the issue isn't as bad. In fact on our local Moodle 3.3 test site the box is big enough in Chrome on Ubuntu 16.04, but not in Chrome on Windows 7.
