If creating a 'link' post, changing the link's auto-generated title, then moving away from the page; upon returning the title has reverted back to the original auto-generated one.
To recreate:
• Click on yellow 'post' button
• Choose 'link' button
• Paste a URL into the URL field
• Visibly change the title after it has been auto generated
• Click away your link post page
• Return back to the link post page that you were creating.
Problem:
This could prove frustrating for users who take their time tweaking a link's creation before posting it.
