Is it possible to render a tooltip on a disabled Material UI Button within a ButtonGroup without breaking the layout?

I'm trying to create a Material UI ButtonGroup with disabled buttons and tooltip.

The following code block shows the buttons correctly, but as described here (https://material-ui.com/components/tooltips/#disabled-elements) disabled elements cannot be provided with a tooltip.

<ButtonGroup>
    <Tooltip title={"This is button A"}>
        <Button>{"Button A"}</Button>
    </Tooltip>
    <Tooltip title={"This is button B"}>
        <Button disabled>{"Button B"}</Button>
    </Tooltip>
</ButtonGroup>

But if I add a span around the disabled button the group layout will be destroyed.

<ButtonGroup>
    <Tooltip title={"This is button A"}>
        <Button>{"Button A"}</Button>
    </Tooltip>
    <Tooltip title={"This is button B"}>
        <span>
            <Button disabled>{"Button B"}</Button>
        </span>
    </Tooltip>
</ButtonGroup>

There are two aspects about a disabled button that get in the way of the tooltip behavior:

1. As mentioned in the docs you referenced, a disabled <button> element (independent of Material-UI) does not fire events in a manner to support proper behavior of the Tooltip.
2. Material-UI specifically disables pointer-events in Material-UI's ButtonBase component (leveraged by Button) when it is disabled.

The second problem can be addressed by overriding Material-UI's disabled styling to allow pointer events:

import MuiButton from "@material-ui/core/Button";
import { withStyles } from "@material-ui/core/styles";

const Button = withStyles({
  root: {
    "&.Mui-disabled": {
      pointerEvents: "auto"
    }
  }
})(MuiButton);

The first problem can be addressed by using Button's component prop to use a <div> element instead of a <button> element. Disabled button elements do not receive click events, so in order to have the Button still behave in a disabled fashion, this code removes the onClick prop when it is disabled.

  const ButtonWithTooltip = ({ tooltipText, disabled, onClick, ...other }) => {
    const adjustedButtonProps = {
      disabled: disabled,
      component: disabled ? "div" : undefined,
      onClick: disabled ? undefined : onClick
    };
    return (
      <Tooltip title={tooltipText}>
        <Button {...other} {...adjustedButtonProps} />
      </Tooltip>
    );
  };

Below is a working demonstration with Buttons B and C both disabled. Buttons A and B use the approach outlined above and Button C is a regular Material-UI Button without a Tooltip for comparison. The additional Button below them toggles the disabled state of B and C.

import React from "react";
import Tooltip from "@material-ui/core/Tooltip";
import MuiButton from "@material-ui/core/Button";
import { withStyles } from "@material-ui/core/styles";
import ButtonGroup from "@material-ui/core/ButtonGroup";

const Button = withStyles({
  root: {
    "&.Mui-disabled": {
      pointerEvents: "auto"
    }
  }
})(MuiButton);

const ButtonWithTooltip = ({ tooltipText, disabled, onClick, ...other }) => {
  const adjustedButtonProps = {
    disabled: disabled,
    component: disabled ? "div" : undefined,
    onClick: disabled ? undefined : onClick
  };
  return (
    <Tooltip title={tooltipText}>
      <Button {...other} {...adjustedButtonProps} />
    </Tooltip>
  );
};

export default function App() {
  const [bAndCDisabled, setBAndCDisabled] = React.useState(true);

  return (
    <>
      <ButtonGroup>
        <ButtonWithTooltip
          tooltipText="This is Button A"
          onClick={() => console.log("A")}
        >
          {"Button A"}
        </ButtonWithTooltip>
        <ButtonWithTooltip
          tooltipText="This is Button B"
          onClick={() => console.log("B")}
          disabled={bAndCDisabled}
        >
          {"Button B"}
        </ButtonWithTooltip>
        <MuiButton onClick={() => console.log("C")} disabled={bAndCDisabled}>
          {"Button C"}
        </MuiButton>
      </ButtonGroup>
      <br />
      <br />
      <MuiButton
        variant="contained"
        onClick={() => setBAndCDisabled(!bAndCDisabled)}
      >
        Toggle disabled for B and C
      </MuiButton>
    </>
  );
}
