Fix quick navigation to entries
On the orca list I've requested a feature that quick navigation feature should not take focusable state into account when looking for buttons and toggle buttons. @joanmarie generalized it to other quick navigation elements as well. However mayson has identified a problem where orca is no longer able to navigate to text entries quickly. This is an attempt at fixing that. It should now be possible to take advantage of recently implemented better discoverability of non focusable elements on the web and keep quick navigation to editable content working fine.
