Fix: Layout breaks when nesting "Wide Alignment" blocks #19

[qarayahya]

Fixes: #19

This issue appears to have been caused by this line : width: calc(var(--container-width-narrow) + 250px) in the .alignwide class declarations for pages and single posts:

   .wp-block-query.alignwide,
    .single .entry-content .alignwide {
        margin-left: -125px;
        margin-right: -125px;
        max-width: calc(var(--container-width-narrow) + 250px);
        width: calc(var(--container-width-narrow) + 250px);
    }

Why this breaks the layout:

When a "Wide" block is placed inside another "Wide" block, the inner block still tries to expand by that extra 250px
