Broken out from bug 22194.
Steps to Reproduce:
Tested using r40102.
1. Go to:
2. Enter a value in the box under "Search by UniProt Accession", such as
3. Hit SEARCH
4. After the resulting page has loaded, hit the back button in the browser.
You get the "Are you sure you want to send a form again?" dialog twice.
I am unable to determine if it is a regression due to bug 23342, though this behavior is present in Safari 3.2.1.
I don't think that this is a bug. This search works strangely - the form is submitted twice, so there is a page with submission result in the history (as you can see by clicking and holding Back button in Safari). So, it is correct for Safari to ask about form re-submission when going back to the intermediate result.
I'm seeing the same behavior in Firefox.
The Firefox behavior is slightly different, in that the dialog is shown only once, not twice. To my mind, Opera works correctly. Going back once goes to the intermediate screen, going back again goes to the original search form.
