B5 Bug: Split plane indicator does not match the splt type

It appears that using a combination of the split buttons and the layout menus, will cause Scrivener to lose track of which split (horizontal or vertical) it should ue when a split button is pressed.

A short demo.

Open Scrivener project
Press the split button on the pane to split the pane horizontally.
Select another document from the browser to fill the lower pane.
Select View–> Layout–> Swap documents on the menu (to swap the documents)
Select View–> Layout–> No split on the menu to kill the upper pane.

You should now have a single pane.

Note that the split button on the pane indicates that we should get a horizontal pane if you press it.
So press it …

Oh.

Interesting… Will look into this and fix it.
Thanks!
