GpgOL might show the wrong cryptostate if the ReadingPane / Preview message list is disabled. This happens more often since 4f9c720433aabc37484bc4f365efc5949f8fa3f0 as that commit "fixed" a broken codepath which now works and blocks the ui invalidation on selection change.

While this is a big bug it's not super critical as the crypto state is not in relation to contents. As soon as one views the content of a mail the crypto state is correct.

To reproduce:

• Select a folder with Reading Pane enabled and look at a crypto mail.
• Select a folder with Reading Pane disabled.

--> GpgOL still shows the state of the crypto mail in the ribbon.
