Provide a General Summary of the Issue

The Popover component in React Aria is experiencing an issue where it flips even when there's sufficient space to render the content. This behavior is unexpected and can be frustrating for users. The position calculations of the Popover component do not seem to take into account the maxHeight prop, leading to this issue.

Expected Behavior

The Popover component should only flip when there's not enough room to render the content. This means that if the content can fit within the available space, the Popover should not flip and should instead render the content as is.

Current Behavior

However, the current behavior of the Popover component is that it flips even when there's space to render the scrollable content. This can be seen in the provided code sandbox, where a 1px margin has been added to the top of the Button to increase the available space above the component. Despite this, the Popover still flips to the axis with more space.

Possible Solution

After reviewing the code, it appears that the calculatePositionInternal function does not take the maxHeight prop into account. This is likely the cause of the issue, as the Popover component is not considering the maximum height when determining its position.

Context

Unfortunately, there is no additional context provided to help understand the issue better.

Steps to Reproduce

To reproduce the issue, follow these steps:

Render a Popover with the maxHeight prop.
Add a 1px margin to the top of the Button to increase the available space above the component.

Version

The issue is being experienced with version 1.7.0 of the React Aria library.

Browsers and Operating System

The issue is being seen on Chrome browser on macOS 15.3.1 operating system.

Company/Team

No information is provided about the company or team experiencing the issue.

Tracking Issue

No tracking issue is provided.

Possible Causes and Solutions

There are several possible causes for this issue, including:

The calculatePositionInternal function not taking the maxHeight prop into account.
The Popover component not considering the maximum height when determining its position.
The maxHeight prop not being passed correctly to the Popover component.

To solve this issue, the following solutions can be tried:

Update the calculatePositionInternal function to take the maxHeight prop into account.
Modify the Popover component to consider the maximum height when determining its position.
Ensure that the maxHeight prop is being passed correctly to the Popover component.

Code Example

Here is an example of the code that is causing the issue:

import { Popover } from '@react-aria/overlays';

function App() {
  return (
    <div>
      <Button>
        <Popover
          maxWidth={300}
          maxHeight={200}
          content="This is a long piece of content that should not flip."
        />
      </Button>
    </div>
  );
}

In this example, the Popover component is being rendered with the maxWidth and maxHeight props. However, the Popover component is still flipping even when there's space to render the content.

Conclusion

Q: What is the expected behavior of the Popover component?

A: The expected behavior of the Popover component is that it should only flip when there's not enough room to render the content. This means that if the content can fit within the available space, the Popover should not flip and should instead render the content as is.

Despite this, the Popover still flips to the axis with more space.

Q: Why is the Popover component flipping even when there's space to render the content?

A: The Popover component is flipping even when there's space to render the content because the position calculations do not seem to take the maxHeight prop into account. This means that the Popover component is not considering the maximum height when determining its position, leading to the flipping behavior.

Q: How can I reproduce the issue?
