Why doesn't the .tab-view element with position: sticky property work correctly on iOS and Safari desktop browsers when it is inside a position: absolute container with overflow: scroll? Can you help me understand this bug and find a solution?

The position: sticky property does not work correctly in iOS Safari and Safari desktop when applied inside a position: absolute container that also has overflow: scroll. This is a known limitation due to Safari's rendering of scrollable elements.

1. Understanding the Issue

• Safari (both iOS and desktop) treats position: sticky differently when the parent element has overflow: scroll or overflow: auto. This often prevents the sticky behavior from functioning correctly.
• Absolute positioning detaches the element from the normal document flow, making it harder for position: sticky to calculate its relative positioning.
• Safari requires that the position: sticky element be inside a non-overflowing parent for the sticky behavior to work correctly.

2. Possible Solutions

A. Move the .tab-view Outside the Scrollable Container

• Ensure the .tab-view element is not inside a container with overflow: scroll or position: absolute.
• Instead, place it inside a relative-positioned wrapper higher up in the DOM structure.

B. Use position: fixed Instead

• If a true sticky effect is not required, replace position: sticky with position: fixed and manually adjust the placement.

C. Apply -webkit-transform: translateZ(0);

• Some Safari bugs relate to stacking contexts. Adding -webkit-transform: translateZ(0); to the scrollable container may force hardware acceleration, which sometimes fixes sticking issues.

D. Ensure top is Defined

• Sticky elements require a top value to properly anchor in Safari, such as:
  ```css
  .tab-view {
  position: sticky;
  top: 0;
  }
  ```

3. Alternative: Use JavaScript for Sticky Behavior

If CSS alone does not resolve the issue, use JavaScript (e.g., IntersectionObserver or scroll event listeners) to manually control the "stickiness."

Summary

Safari's handling of position: sticky inside absolute and overflow: scroll containers is a known limitation. The best solutions involve placing the sticky element outside scrollable parents, using position: fixed, or applying -webkit-transform: translateZ(0); for some cases. If CSS fixes fail, JavaScript can be an alternative workaround.
