Scroll bouncing in flipped combobox with multiple items

[wgg-max]

Provide a general summary of the issue here

The scroll of the list popover inside the combobox is bouncing when multiple items are displayed, but only when its flipped automatically. This prevents the user from reaching the items at the end of the list.

🤔 Expected Behavior?

The scroll should not bounce and work as normal like in case of the non-flipped version. Applying shouldFlip={false} on the popover fixes the issue but is preventing the use of auto flipped combobox popovers.

😯 Current Behavior

The scroll bounces towards the end of the list.

I wasn't able to reproduce this. Are there any special system settings regarding scrolling that are enabled? Does this happen in multiple browsers, or just Chrome?

We were able to reproduce this issue on Microsoft Windows 11 Enterprise (Version 10.0.26100, Build 26100) using Chrome 142.0.7444.163. Notably, the issue did not occur on the same Windows configuration when using Firefox 145.0.

Additionally, we reproduced the issue on macOS Sequoia 15.6 with Chrome 142.0.7444.60, Firefox 142.0.1, and Safari 18.6.

All browsers were tested with no extensions enabled and using their default settings.

At this stage, we have not been able to determine whether the root cause lies within the browser or the library itself. We apologize if this falls outside your scope, but since the issue appears across multiple browsers, we wanted to bring it to your attention.
