User is stuck on Reader Preferences screen on iPhone in landscape orientation

[northgardner]

(Related to #3138) When I am reading an article in landscape mode and activate the Reader Preferences menu, there is no way to get back to the article while staying in landscape orientation. I have to turn the device and leave the menu in portrait mode, then turn it again to return to landscape.

I am using an iPhone 13 with iOS 17.1.1 and the latest version of the Omnivore iOS app.
