Using git bisect, I identified the commit that introduced the problem: commit
f70690899d2a6c69495d225214a7279ba8c1ff73,
https://cgit.kde.org/trojita.git/commit/?id=f70690899d2a6c69495d225214a7279ba8c1ff73
Right now I'm using the patch at the bottom as a workaround. That's obviously
not a proper fix but it demonstrates that the way Util::Css::warningBorder is
used causes the problem. How can we fix this properly?
https://bugs.kde.org/show_bug.cgi?id=386351 is probably the same problem as the
diff below works for miqlas as well.
