Overflow with in Free Container

When I have containers that are not a set of overflow attributes and inside this container, add containers with positions free. If I move the free container outside the parent container, all parts that out disappear until I set the overflow visible. if the free container becomes grandchild in this case, I should make all parents overflow. Otherwise, free container stay disappears.
I watched a video recording a year ago, but this issue wasn't there.

No files, tests, or entry points are named. First reproduce the nested free-container case described in the issue, including moving a free container outside its parent and nesting it as a grandchild. Done means the free container remains visible without manually setting overflow on every ancestor.
