Bug 1375833 - Part 2: Set mHistoryID to aSHEntry->DocshellID() in both reload and history navigation. r=smaug The root cause of bug 1326845 is that reloading would apply frame history entries without setting new child docshells' mHistoryID to the entrys' DocshellID. So SHistory can not find corresponding entries for subframes in a consequent GoBack(), and cause history navigation being broken (it would return NS_ERROR_FAILURE). MozReview-Commit-ID: 6syGYkoP1eZ
