reserveScrollbar: true doesn't work with vbox layout (works with anchor layout)

Ext version tested:

• Ext 4.2.1

Browser versions tested against:

• ____
• IE8
• FF3 (firebug 1.3.0.10 installed)
• Safari 4

DOCTYPE tested against:

• html

Description:

• reserveScrollbar: true doesn't work with vbox layout (works with anchor layout).

Steps to reproduce the problem:

• make a layout with 'vbox' layout
• set overflowY: 'scroll' and reserveScrollbar: truebar

See https://fiddle.sencha.com/#fiddle/235
If you click among the tabs, tabs are resized according to whether the view is scrollable or not.
If you change layout to 'anchor', tabs keep their sizes with no matter of any scrollbar. reserveScrollbar works as expected.

The result that was expected:

• reserveScrollbar should have effect

The result that occurs instead:

• reserveScrollbar has no effect

Unfortunantly, reserveScrollbar isn't a property of the vbox layout. The reason it works on anchor layouts is because the anchor layout extends the auto layout which has the reserveScrollbar property.

Thanks, bmacdon1!

The inheritance can be seen in the right column of these pages.
