The ellipsis character added dynamically with CSS text-overflow: ellipsis are excluded from text selections.
Some related behavior:

• If you select the whole line (with a triple-click on the text for instance), it selects the clipped (invisible) text too.
• If you make the sidebar wide so that the text is not clipped, select it, then make the sidebar smaller until some of the text is clipped: the text selection remains the same (Ctrl+C or Command+C would copy the same string).

While that can be surprising sometimes, IMO it's useful behavior so I would keep it as is.

Bugbug thinks this bug is a regression, but please revert this change in case of error.

The ellipsis has no value to be copied -- it's simply a visual marker that the entire URL isn't visible.

I can see adding a context menu to copy the pattern but outside of that I'd call this invalid.
