Oh no, I did not carefully enough read my own report.

This problem still exist but only with the tags tab.

In 17371/josm:

fix #18533: changeset manager: tags tab: width of column (almost) not changeable

• use ReadOnlyTableModel as in PropertiesDialog to allow resizing of column width
• don't allow reordering of column headers in Changeset dialogs (because content doesn't match header if allowed)

[GerdP]

After commiting I found the cause for the problem with the old code.
It uses class TagTable which contains

    @Override
    public Dimension getPreferredSize() {
        return getPreferredFullWidthSize();
    }

This method is called whenever you move the mouse cursor inside the dialog and resets the column widths. I guess it should only be used when the dialog is created, but I have not yet found how to change that.

Maybe, breaking long values into several lines could be an enhancement to display more/all content.
