I found a GitHub issue in CodeMirror's repo that addresses the same problem:  https://github.com/codemirror/codemirror5/issues/6630

Option-D, Option-F and Option-B are legacy emacs shortcuts that no longer work on modern Macs.

CodeMirror already removed Option-D, Option-F and Option-B bindings in https://github.com/codemirror/codemirror5/pull/6631, so the latest CodeMirror does not have this problem.
