// Test Summary:
|
|
// 1. Open about:sessionrestore where formdata is a JS object, not a string
|
|
// 1a. Check that #sessionData on the page is readable after JSON.parse (skipped, checking formdata is sufficient)
|
|
// 1b. Check that there are no backslashes in the formdata
|
|
// 1c. Check that formdata doesn't require JSON.parse
|
|
//
|
|
// 2. Use the current state (currently about:sessionrestore with data) and then open that in a new instance of about:sessionrestore
|
|
// 2a. Check that there are no backslashes in the formdata
|
|
// 2b. Check that formdata doesn't require JSON.parse
|
|
//
|
|
// 3. [backwards compat] Use a stringified state as formdata when opening about:sessionrestore
|
|
// 3a. Make sure there are nodes in the tree on about:sessionrestore (skipped, checking formdata is sufficient)
|
|
// 3b. Check that there are no backslashes in the formdata
|
|
// 3c. Check that formdata doesn't require JSON.parse
