Steps to reproduce

I have a table with each row containing a button with tooltip:

<Tooltip title={tooltipTitle}>
  <Button
    className="button-link table-deletion-button"
    onClick={handleClickMethod}
    disabled // This only happens when the disabled prop is set to true
  >
    <MyIcon name="escape_1" />
  </Button>
</Tooltip>

This is what I get in the HTML –– the <span> gets the button classes, instead of the button having them

What is expected?

Tooltip should not get its children classes

What is actually happening?

Tooltip gets its children classes
