Describe the bug
When resizing-smaller a fixed Column on RadzenDataGrid with another fixed column to the right the new free space will be white while draging resizing bar. Next fixed column will only snap to smaller space when stop dragging the resize bar. Until then it wil stay hovering where it is while non-fixed columns are moving below it with resizing.

To Reproduce
Steps to reproduce the behavior:

  1. Go to Demo page
  2. Make the photo column bigger (that works like intended for some reason)
  3. Now reduce the photo column width again
  4. See error

Expected behavior
The fixed column does follow the resizing also on getting smaller, not only on getting bigger

Screenshots

Desktop (please complete the following information):

  • Browser chrome
  • Version latest on creation

Additional context
The resizing to smaller does work somewhat as long as the drag position is bigger than the last/current stored width.
So dragging the column bigger and again smaller will keep the next column attached like expected as long as the resize width is bigger than the initial. As long as aou are dragging. When going lower than the initial width it will start showing the white space and the next non-fixed column will be following resizing with the whitespace the width of the initial width, going under the fixed stuck column
