Description Devin Lin 2020-04-25 20:40:45 UTC 
SUMMARY
With Kirigami.ScrollablePage, the page title header does not stay after scrolling down, and then scrolling back up.

STEPS TO REPRODUCE
1. Open Kirigami Gallery with QT_QUICK_CONTROLS_MOBILE=1
2. Resize window so that the sidebar is hidden.
3. Go to the "List view of simple cards" page
4. Scroll down so that the header is gone, and scroll back up

OBSERVED RESULT
The header is unable to stick.

EXPECTED RESULT
The header sticks when scrolling back up.

This seems to be caused by https://invent.kde.org/frameworks/kirigami/-/commit/2e9355a6e584f392d19ba870054c5fc590782921
Comment 2 Nicolas Fella 2020-07-13 21:42:19 UTC 
There are two issues:
- The last list item is cut off
- When scrolling all the way up the header disappears

The header is supposed to slide away.

the actual bug is that sometimes it doesn't slide back in

I think this was fixed when the header behaviour was redone :D
