Member columns don't auto-resize when the relation editor is resized

See the attached screenshots, adjusting the horizontal space of the relation editor will cause JOSM not to update the new space that the columns have.

Dialog doesn't keep up with its new dimensions

Clicking on it for resizing causes it to snap to its correct size

I saw this myself quite often. Sometimes column width (or table width) is adjusted, sometimes it isn't. I tried

• listening to adjustment events o the JSplitPane
• listening to property change events for dividerLocation in JSplitPane

and then {{{validate}}-ing the panel with the table, but no luck so far.

@stoeckr, @jttt: any hint?
