[Bug]: userEvent.keyboard not working in play functions

[JealousGx]

Describe the bug
I am facing an issue with the keyboard or type methods of userEvent.

TagsField.play = async ({ canvasElement }) => {
  const canvas = within(canvasElement);

  // wait for scripts to load
  await new Promise((resolve) => setTimeout(resolve, 1500));

  const event = canvas.getByLabelText("Included brands", { selector: "input" });
  await userEvent.type(event, " ");

  await new Promise((resolve) => setTimeout(resolve, 1500));
  await userEvent.keyboard("{backspace}{backspace}");
  await userEvent.keyboard("{backspace}");
};

I have this piece of code that plays the story. And I have also modified the functionalities for backspace to something else. Basically, a span is created upon pressing enter and when backspace is pressed, the whole span is removed and this functionality is achieved through javascript and I am also injecting that javascript code into the story as well. It's working fine with locally run webpack with human interaction, but when it's tested on storybook with testing-library, it doesn't seem to be doing its functionality. In fact, {backspace} doesn't remove any character at all.

FYI: I am using Storybook v7.4.3 and @storybook/testing-library v^0.2.1

This functionality was working fine with storybook v6.5.x but after migrating to v7.4.2, it stopped working.

To Reproduce
Steps to reproduce the behavior:

1. Write any story that uses the above code.
2. Run the storybook.
3. Go to the story & see the error.

Expected behavior
Expected @storybook/testing-library to work fine even after updating the storybook version to 7.4.3
