Shortcuts missing when rendering custom textarea

When I render a custom textarea, I'm not quite sure how you can make the shortcuts apply. I've tried triggering the method from the onChange handler on the new textarea, but I get Argument of type 'ChangeEvent' is not assignable to parameter of type 'React.KeyboardEvent | KeyboardEvent'.

Obviously this is because the onChange event is not the correct place to execute the function, but even when I try using onKeyDown or onKeyUp method, it still does not apply the shortcuts. Any thoughts on how I can apply the shortcuts to a custom textarea? (Note: I'll eventually be creating a custom component here, but I'm trying to make it work on the most basic example first)

<div className="markdown-container" data-color-mode="light">
	<MDEditor
		textareaProps={{
			placeholder: "Write in markdown",
		}}
		value={markdown}
		onChange={handleChange}
		onPaste={async (event) => {
			await onImagePasted(event.clipboardData, setMarkdown);
		}}
		previewOptions={{
			remarkPlugins: [],
			rehypePlugins: [[rehypeSanitize]],
			rehypeRewrite(node, index, parent) {
				if (node.type === 'element' && node.tagName === 'a') {
					node.properties = { ...node.properties, target: '_blank' };
				}
			},
		}}
		components={{
			textarea: (props, opts) => {
				const { dispatch, onChange, shortcuts } = opts;
				return (
					// @ts-ignore
					<textarea 
                                              {...props} 
                                              onChange={(e) => {
                                                  if (dispatch) dispatch({ markdown: e.target.value });
                                                  if (onChange) onChange(e);
                                                  //~~~~~~THIS LINE BELOW DOES NOT WORK~~~~~
                                                  if (shortcuts) shortcuts(e, commandsList);
                                              }}
                                          />
				);
			},
		}}
		commands={commandsList}
	/>
</div>

Start with the MDEditor components.textarea customization shown in the issue and trace how opts.shortcuts receives keyboard events. Compare the event types used by onChange, onKeyDown, and onKeyUp; done means shortcuts work in the custom textarea without the reported type error.
