We don't handle splitting stacks the same way depending on the orientation of the split.

to Repoduce:

Start with a fresh Java perspective

Drag the Problems view to split the Package Explorer side-by-side

Drag it back where it was...notice that the Package Explorer is the same size it was before the split

Now drag it to split the Outline view side-by-side and back again

Notice that the Outline does *not* go back to its original size

This is the result of an 'optimization' that tried to minimize the number of PartSashContainers we create by allowing more than two if the orientation is the same direction. but this leaves the 'weights' incorrect. It's better to remove the optimization, allowing better control over the weights. Note that this is not a performance issue since we share a single Composite.
