Screenshot of bug showing that the 'Post' button disappears if you add carriage returns.
If you add a lot of carriage returns in the text box of a feedback form in overlay mode, the 'Post your feedback' button disappears.
What's needed is a scrollbar, so that you can go up and down your feedback, without hiding the buttons.
See attached screenshot. I reproduced that bug on Option 2, and I believe it's also present in Option 1, though I no longer can access this overlay mode on prototype.
Here is the URL I am now using to test this:
(It is possible that the URL tags may have changed; if so, please provide the updated URL that would cause the 'Improve this page' button to display for Option 1)
P.S.: For what it's worth, here is the angry post on the AFT5 page that prompted this bug report:
