When clicking outside of a cell while editing the same, the cell changes from "edit mode" (textfield) to display mode. However, changes made to the cell text are discarded.
This does not match user expectation experienced in other table-based editing frameworks.
Request: Either do not allow to leave the textfield via mouse click at all, or make the changes persistent
For means to discard changes quickly, the <ESC> key would be a good option.
