The split box may contain a focusable field that uses a focus glow (#scout.focus-border()), e.g. TreeField, Button etc. Because split box sets overflow: hidden, the glow won't be fully visible. Overflow: hidden is necessary if the content has a min size and won't shrink anymore even if the splitter is moved further.
With the new overflow: clip property it is possible to define a clip-margin to show the focus glow.
Unfortunately, Safari does not support the clip-margin yet https://bugs.webkit.org/show_bug.cgi?id=236153
