In the (default) Compositing workspace, closing one of the left-hand side panes so that there are only 2 panes next to each other, causes the maximise function to fail for the right-hand side pane (Properties by default). Seems to have broken between 9.0v3 and 9.0v4 as the problem is not present in 9.0v3.
Customer reported version
Nuke 10.0v4
Steps to reproduce
1) Open Nuke into the default Compositing workspace
2) Right-click on 'Viewer1' and 'Close Pane'
3) Hover over the Properties pane
4) Press Spacebar to maximise the pane
5) Instead of maximising, it should shrink
Reproduced by support
10.0v4 - Windows 10, OSX 10.10.5
10.0v1 - Windows 10, OSX 10.10.5
9.0v9 - Windows 10, OSX 10.10.5
9.0v4 - Windows 10
Expected behaviour
For the pane to maximise correctly
Actual behaviour
The pane shrinks and is pushed to the side of the screen
