ExtJs 6.7.0- treePanel with rowWidget misaligned when using locked column

Question

I have an Ext.tree.Panel with a rowWidget using Ext.grid.Panel, when I lock the first column of Ext.tree.Panel the rowWidget expansion doesn't expand the locked column all the way.

I understand that when I lock a column the tree/grid split into 2 synced grids, one for the locked columns and another with the rest. The rowWidget expansion occurs only on the unlocked section.

I would like to know if there's a way to properly sync the expansion of both grids.

I built a fiddle reproducing the situation from image above. If line 41 (locked: true) is removed, the locking on column, it works just fine.

TREEPANEL_LOCKED_ROWWIDGET

Thanks in advance!

Answer 1

You could force a refresh on the locked grid when the row widget is expanded;
