I was about to ask whether we really need that complicated approach as
we don't change the layout dynamically. However, after some experiments,
it turns out there's no easier way, though I consider that a bug.
Namely, once you enable line wrapping using label.set_line_wrap(True),
the label no longer fills the entire horizontal space allocated to the
label by its parent with text (though it does _align_ within this space,
respecting label.set_alignment()). If you don't enable line wrapping,
the label will use all the allocated horizontal space to display the
text, but cut it off (as expected).


For the proxy settings this worked well enough because the text size
matched the fixed default size of the label reasonably well on all of
the systems I tested with.

While configuring the proxy still requires scrolling, at least one would
be able to see that there's something to configure, i.e. the
discoverability concern would be addressed. It's by a rather tight
margin, though. On what systems did you test? I'm worried it might just
"fall off" the screen on tighter setups (smaller screen or larger font
size). Especially if the scrolled area is barely larger than the screen,
the scrollbar blends into the surroundings a bit too well.
