Describe the bug.

I was exploring the Roadmap page and noticed a scrolling behavior that seems unintentional. When I click on a roadmap item card, a modal popup appears with the description. If I scroll down inside this modal and reach the bottom, the main background page starts scrolling instead of the scroll stopping at the end of the modal content.
I wanted to confirm if this "scroll chaining" behavior is intended or if the background scroll should be locked while the modal is open?

Expected behavior

Typically, when a modal is open, the background page should be locked (non-scrollable) to keep the user's focus on the modal content. The scroll should be contained entirely within the popup.

How to Reproduce

Go to https://www.asyncapi.com/roadmap
Click on any roadmap item card that has a long description
Scroll down inside the popup modal.
Continue scrolling once you reach the bottom of the modal.
Observe that the background page behind the modal begins to scroll.
