I’ve just tried filling up a flow panel with links, and once I get to 8 weird things start to happen.
This is the first of the (see gif below). I cannot add any more links after 8. Nothing happens when I try (this is all in the IDE by the way, I’ve not tried programmatically).
Once I hit the limit, the 8th element seems to be un-selectable. Then suddenly it swaps itself out for one I’d previously tried to add to the end, as if there was a massive (1-2 minute) delay to my drag-drop action. Then selecting that link highlights the link below it. I’m not explaining it well - take a look at the gif and it might make more sense.
Link to the app if it helps any :
