When using the alignment function on content across multiple different frames on the page, it did not align them with each other as described in the documentation, which worked correctly in previous versions.
However, if these frames (Frame1, 2, 3) are nested within a parent frame (FrameA), it is possible to align the elements within Frame1, 2, 3 with each other.
This achieves my goal, but it’s overly complex.
