(Core :: DOM: Navigation, defect)

If you use the 'ScreenSize' selector on the page in question then all of the
data you have entered into the form is lost, even if you go Back.  I cannot be
more specific but I hope someone can narrow this down.

To be clear, I am not talking about the 'new' form being empty, I am talking
about the 'old' form being empty if you hit back after changing size.

Reproducible: Always

Steps to Reproduce:
1.  Visit page
2.  Type in a message
3.  Change ScreenSize
4.  Go Back
Actual Results:  
Empty form

Expected Results:  
Restored the form to the way it was before ScreenSize was changed

Confirmed on Linux.  As another simple test, just load the page, type something
in the textarea, then hit reload.  The text should be preserved, but is not.

this occurs because of the <form> between the <table> and <tr> and then the
hidden <input>s.

dupe of "Misplaced form element and hidden input element(s) break form value
restoration when pressing Back"
