_WKSessionState blobs without history entry data should deserialize
https://bugs.webkit.org/show_bug.cgi?id=275757
rdar://122049041
Reviewed by Brady Eidson.
Back in 2016 in r198468 (<rdar://25064718>), we made a change to conditionally
serialize
sessionHistoryEntryDataKey. But when we deserialize session state, we
unconditionally fail if we
don't find sessionHistoryEntryDataKey. So we have a large number of session
data blobs in the wild
which simply don't deserialize, which looks like a tab with an empty
back/forward list in the
browser.
Fix this by allowing deserialization of blobs missing a
sessionHistoryEntryDataKey.
