A node would not show the "Collapse/Expand" arrows (caused by87c011f8bbwhich moved the drawing code for the input nodes a new `custom_draw_fn` callback on the socket declaration). Related fix:7f07124d30So in order to resolve, make sure we have correct conditions to show the expander and also make sure we draw the custo buttons in appropriate places. NOTE: not sure if there are better ways to achieve the correct UI split alignment, since we draw with empty labels, I had to flag with `UI_ITEM_R_SPLIT_EMPTY_NAME` in the new `custom_draw_fn` callbacks.
