Grid not refreshing after browser window resize

  1. Open Vaadin Framework 8 grid sample (https://demo.vaadin.com/sampler/#ui/grids-and-trees/grid/features)
  2. Start resizing browser window - make it smaller / bigger / smaller / bigger
  3. After few resizes grid starts to look really bad (see attachment)

Tested on Firefox 67.0 (64-bit) Centos Linux.

What you see there is not actually issue with Grid, but Sampler application, where Grid has been wrapped in resizeable layout, but the application does not check reasonable bounds for Grid minimum height or width. Hence Grid appears broken.
