In Backlog, I want to keep scrolling up and down the backlog (middle panel), without any movements in the LHS (Epics panel) or RHS panel (Details panel).
However, all 3 panels seem to be scrolling together, even if there's no content.
Steps to reproduce
1) Have a large backlog
2) Open LHS and RHS panels
3) Try to scroll down the backlog, expecting that position in the LHS/RHS remains fixed
4) Actual outcome: all 3 panels are scrolling together, which does not make sense as there's nothing but white space in LHS and RHS panels.
