Dungeons purchase warnings are displayed behind scroll bar

The bug

When hovering over the "Buy now" button on the DLC tab of the Minecraft Dungeons section while using macOS or Linux, a warning message is displayed informing the user that Minecraft Dungeons is not available on their operating system. However, when viewing this warning on a DLC that includes a scroll bar, the warning is displayed behind the scroll bar, as seen in the screenshot below.

One could expect that this warning is displayed above the scroll bar.

How to reproduce

1. On macOS (or Linux?), navigate to the Minecraft Dungeons tab -> select DLC
2. Hover over the "Buy now" button for "To the End"
   -> The purchase warning is displayed behind the scroll bar
