In line 77 in the file SidebarControl.xaml IsTabStop is also set to False. Can you fix that as well?

@duke7553 Can you look at this?

@Thomas1664 This property value doesn't affect functionality, does it?

@duke7553 It does. Disabling tab stop will prevent keyboard tab navigation for the UI element

@Jaiganeshkumaran @Thomas1664 Sorry, but what you said is incorrect for this case.

The changes I already made allow for using tab because tab stop is enabled for the items themselves already. Unless you want to have a discussion about removing the custom template for these sidebar items altogether (which I'd support), there is no need to change the template value because it already works fine with my changes.

Would enabling the template value for the tab stop give us any more benefits? In my testing, the sidebar items already work as intended.

@duke7553 Although your changes already work, it would be better for code style if you removed the remaining IsTabStop. Furthermore, it may save us from future bugs.

@Thomas1664 Since the template itself was redundant, I just got rid of it so we use the standard resources now.
