find
Returns all blocks that overlap an exclusion area on their page.
The engine never moves a block to satisfy an exclusion area. A scene loaded from a file, or laid out through the API, can legitimately overlap one, and silently repositioning it would lose the author's layout. Use this to warn or to highlight instead.
An exclusion area that is hidden, or that is not on a page, reports nothing. exclusionArea/constrains is not read: an advisory exclusion area has no push, so a warning is the only thing it has. A group that straddles an exclusion area is reported instead of the blocks inside it.
Return
a list of block ids that overlap an exclusion area, sorted ascending.
