fix(_updateItemsInRange) large items should not disappear
This is to address #1573
Adds a condition to only hide items when the group is not visible and height is defined.
The problem seems to be happening when a group is redrawn and height is temporarily
undefined
.Group._updateItemsInRange
is called before the group height gets defined inredraw
. When height is undefined in_updateItemsInRange
, it considers the group invisible and hides the items (lines 908-914 Group.js). Then for the next paint, when height is defined, the group is now visible but there are no items.
