If you click on a scrollbar (Or if you click inside the canvas but not actually on a cell/header/row) the selected rows getting unselected.
This was no issue in 5.2.1.

You can reproduce this behavior it the storybook:

I would say it should only be possible to unselect a row via the rowMarkers!?

Would be great if this can be fixed. ;)

Thank you, for the awesome GlideTables!
