fix(web): truncate preview host label when no page name is resolved#4486
Merged
Conversation
The preview address bar rendered the host fallback (previewLabel) in a `shrink-0` span, so a long sandbox host was clipped mid-string by the container instead of truncating with an ellipsis. It also still rendered the separate route-path span, whose competing `flex-1` stole half the bar and forced the host to truncate far too early (plus a redundant trailing `/`, since previewLabel already includes the path). Now the label span truncates (`min-w-0 flex-1 truncate`) in the no-page-name case and keeps `shrink-0` when a real page name is shown, and the route-path span only renders when there's an actual page name.
