Tooltip "persistOnClick" property doesn't seem to work

Hey,
I have a Tooltip wrapping a Button within a segemented ButtonGroup.
When clicking the Button the Tooltip disappears despite the persistOnClick prop which could be irritating.
Here the code:

<ButtonGroup variant="segmented">
  <Button id="templateNameField" disabled={true} size="large">
    Default
  </Button>
  <Tooltip persistOnClick dismissOnMouseOut content="Next Template">
    <Button icon={SelectIcon} size="large" accessibilityLabel="Next Template" onClick={() => {}} />
  </Tooltip>
  <Button icon={ReplaceIcon} size="large" accessibilityLabel="Change Template" onClick={() => {}/>
</ButtonGroup>

Thanks in advance!
