Current behavior:

Currently, the ios large (collapse) header is able to be between the two states when releasing the pointer via scroll. It then looks like:

Expected behavior:

As far as i see, native it switches either to the expanded or collapsed state, determined by how far the transition was done when releasing.

研究方向
Investigate the iOS large title header component in Ionic Framework (likely in core/src/components/header). The bug is that the header remains between expanded and collapsed states when released. The fix should snap to one state based on scroll position threshold. Refer to native iOS behavior for reference. No linked PRs or assignees, so the issue is open for contribution.
