Tweet compose view disappears without user intervention if url takes more than a few seconds to retrieve


When posting a tweet with an accompanying URL, the tweet compose screen disappears without the user tapping cancel or post if the URL takes more than a few seconds for Twitter to retrieve the page and create a snapshot for the tweet compose view. This happens whether I use Twitter from within UIActivityViewController, or SLComposeViewController, or TWTRComposer. It also occurs whether using iOS 8.x or 9.x.
