Keep all tabs mounted

[riwu]

Describe the bug

Can we add support to either mount all tabs immediately, or lazy loading -- once mounted, don't unmount them (unless the tab is closed)?

This is useful for persisting local states when switching tabs.

The default behaviour is to lazy load tabs and keep mounted once loaded, state is maintained when tabs are moved.

You can force tabs to initially load by setting the tab attribute enableRenderOnDemand or the global attribute tabEnableRenderOnDemand to false
