I have noticed that in a treegrid, when a text is larger than the column itself, a “…” is added to the text. However, this “…” is overlaying the actual text, and is not ammended to the text (the text should also be shortened).
Have a look a https://demo.vaadin.com/sampler/#ui/grids-and-trees/tree-grid/file-system-data-provider
and try to resize the first column.
Standard grids seems to work. Last column in treegrid also seems to work.
