GtkTreeView without GtkScrolledWindow suddenly scolls.
I have the following widget graph:
- GtkScrolledWindow
- GtkViewport
- GtkBox
- GtkBox
- GtkHeaderbar
- GtkTreeView
- GtkBox
- GtkHeaderbar
- GtkTreeView
- ...
- GtkBox
- GtkBox
- GtkViewport
If I expand a row in the last tree view, it does not properly expand to full size and it is suddenly possible to scroll the tree view with the keys up/down. Note: there is no GtkScrolledWindow directly a parent of the GtkTreeView.
I attached a movie of the issue.
