BlockMenu plugin for @atlaskit/editor-core

/**
 * Unwraps a layoutSection node, extracting content from all columns.
 * Works with any number of columns (2, 3, etc.).
 *
 * Example:
 * layoutSection(
 *   layoutColumn(p('a'), p('b')),
 *   layoutColumn(p('c')),
 *   layoutColumn(p('d'))
 * )
 * → [p('a'), p('b'), p('c'), p('d')]
