When navigating a tree, the layout may unexpectedly move

[cigamit]

Describe the bug
On the dark them, and in other themes, when showing and hiding the tree, the size of the margin either is restored improperly, or the margin creeps to the left through successive navigations.

To Reproduce
Steps to reproduce the behavior:

1. Goto dark theme
2. Goto tree and start to navigation to different banches
3. Not that the left margin continually increases
4. Goto any theme, and hide the tree navigation
5. Unhide the tree, and notice the graph area has lost it's left padding

Expected behavior
When you hide and show the tree, the restoral of the tree should result in previous view. Navigating the tree should not change the width of the navigation area.

Wasn't this raised in an earlier issue too? Or maybe that one has already been closed.

Yea, it was closed. This was related. Noted in testing that after you hide and restore the tree, that the graphs to the right were creeping into the Tree area.
