1195069 - Restoring reader view tab doesn't restore the original scroll position

Status: RESOLVED DUPLICATE of bug 1153393

(Firefox :: General, defect)

Description

[Xidorn Quan [:xidorn] UTC+11]

Steps to reproduce:
1. open an article page, e.g. https://blog.mozilla.org/blog/2015/08/11/firefox-brings-fresh-new-look-to-windows-10-and-makes-add-ons-safer/
2. click the "Enter Reader View" to enter reader view
3. scroll down to some random position
3. close this tab
4. undo the close (via Ctrl-Shift-W / Cmd-Shift-W or "Undo Close Tab" in the context menu of toolbar)

Expected result:
the reader view page scrolls to the previous position

Actual result:
the page starts from the top


This also happens when you restart Firefox with "Show my windows and tabs from last time".

(BTW, I think there should be a component of Firefox in Bugzilla about Reader View, shouldn't it? I only found one for Firefox Android)
