6.0.4-alpha17 introduced a bug where if both axis are in a scrollable state, scrolling on one axis causes the other to scroll as well.
For example scrolling the X axis to reveal more columns causes the Y axis to scroll the rows. Reaching the end of the X scroll of columns leaves the Y scroll at the end of the rows.
This behaviour is not present in 6.0.4-alpha16 but is in builds after.
preventDiagonalScrolling does not mitigate the behaviour.
