Reverting changes in "Enable 'links' when reloading document"
Default sidebar page

When the sidebar page set by the document metadata
is not supported, it falls back to thumbnails.
Enable supported pages after reloading

When a document is reloaded, the supported pages
in the sidebar should be enabled.
Sidebar selects correct page after reloading

Once a document is reloaded, if the current
sidebar page is no longer supported, it should
change to the first supported page. Otherwise, it
does not change pages.
