🎯 Goal

Fix Channel List search bar disappearing in rare cases. If the number of items was about 10, the channel list would be scrollable initially with the Search Bar shown. After scrolling to the bottom, the search bar would disappear, losing the scrollability.

🛠 Implementation

The alwaysBounceVertical should be set to true so that the scrollability is never lost and the Search Bar reappears again.

🧪 Manual Testing Notes

• Open the channel list with "General Grievous"
• It should have exactly 10 channels only in the Channel List
• Scroll to the bottom and up again
• Search bar should always be visible
