Bug Description

Actual Behavior

When clicked, the InfoLabel popover component should be attached to the DOM as a child of the element passed to the control, e.g.

<InfoLabel
  {...props}
  infoButton={{ popover: { mountNode: popoverRoot } }}
/>

Expected Behavior

When clicked, the InfoLabel popover component is attached to the DOM as a sibling of its <button>.

Note that this behaviour was previously supported, albeit in a slightly different fashion, back when the component was simply known as InfoButton, via its popover property, e.g. <InfoButton {...rest} popover={{ mountNode: popoverRoot }} />.

In the provided minimal repro, we can see that the mountNode property provided does indeed point to a valid DOM element.

Hi @brhallin @Hotell
Can I try resolving this bug?

It appears there are two issues:

1. divRef.current is passed as null because after the initial render, when divRef gets its value, the component does not re-render.
2. The infoLabel is not functioning correctly when passing mountNode in the infoButton prop. The reasons are:
   a. The infoLabel uses infoButton, which in turn uses PopOver.
   b. The PopOver surface uses Portal when the surface is not inline.
   c. In useInfoButton.tsx, the inline prop has a default value of true, which is causing the issue.
   d. We should either pass inline as false or have inline automatically set to false when mountNode is passed.

Thanks!

Thanks for investigating the issue and identifying the problem!

We should either pass inline as false or have inline automatically set to false when mountNode is passed.

That's entirely up to the Fluent team, so I won't comment on the best decision. My team, however, now has a way forward -- we'll just add inline: false along with the mountNode prop, and we'll be unblocked.

Sure but we are halfway.

on passing inline: false along with mountNode in infoButton, do create the infoLabel popover inside the mountNode element, but the positioning of the popover is still at infoButton.

Reference: popover is created and gets added in mountNode div element but still shown above the infoButton

[brhallin]

FWIW, in our use case, with the Canvas environment, the mountNode property we're providing points to a valid DOM element and with the addition of inline: false, it's now respecting that element.

It's possible that the minimal demo I provided is faulty.

great!
