Hi everyone I can confirm this happens in chrome and chromium with the "#overlay-scrollbars" flag (chrome://flags) enabled. The current workaround would be to disable "#overlay-scrollbars". This is related to the property overflow for .CodeMirror-scroll which is currently set to
overflow: scroll !important; in "codemirror.css". It would be solved by using overflow-y: hidden; overflow-x: auto; as seems to be set in "codemirror.less". Greetings Ray
