Non-custom scrollbar appears when collapsing and extending Quick Play selector

The bug

On collapsing and reopening the Quick Play selector options, a non-custom scrollbar appears at the bottom of the launcher when the launcher is at its default size. It disappears when hovering to another Quick Play selector option.

How to reproduce

• Have the launcher at its minimum/default size and Quick Play enabled.
• Click the fold icon in Quick Play, then click it again to expand the options.

→ The launcher displays a side scroll bar at the bottom of the window for no apparent reason.

Expected result

No non-custom scroll bar is displayed.
