There was a problem hiding this comment.
I noticed that it means occupiedRects may no longer be in block order (as it's sourced from an object).
I think it's ok though, the only thing I can see it's used for is this code, which doesn't depend on the ordering:
const isCellOccupied = occupiedRects.some( ( rect ) =>
rect.contains( column, row )
);There was a problem hiding this comment.
Yeah order isn't important.

See #63976.
Stacked onto #64321.GridPopoverwas callinggetBlocks( gridClientId )which returns a new array reference every time any inner block in the grid changes. This causes all ofGridVisualizerto update when typing into a grid cell.We only care about when one of the attributes in
style.layoutchanges, so I've fixed this by adding a new private selector that returns only thestylekey of the given blocks.Before:
