The ToastUI Editor consumes its content via the `initial-value` prop and then internally
manages changes. If we desire the `v-model` to work as expected, we need to manually call
`setMarkdown`. However, if we do this in each v-model change we'll continually prevent
the editor from internally managing changes. Thus we use the `previousMode` flag as
confirmation to actually update its internals. This is initially designed so that front
matter is excluded from editing in wysiwyg mode, but included in markdown mode.
