Description In SP Page Builder 5, the "XL" breakpoint/container range (specifically covering @media (min-width: 1200px) up to @media (max-width: 1399.98px) with a container max-width: 1140px) is missing.

While present in SPPB 4, the current responsive breakpoints skip XL and jump directly between Large (LG) and Extra Extra Large (XXL). This gap creates broken layouts and forces developers to write manual CSS overrides for screen widths between 1200px and 1399px.

Expected Behavior SP Page Builder 5 should align with standard Bootstrap 5 grid breakpoints, specifically supporting the XL breakpoint (@media (min-width: 1200px) with standard container max-width 1140px).

Actual Behavior The XL breakpoint range is skipped entirely, leaving @media (min-width: 1200px) unmanaged in the UI controls.
