Is this idiomatic? I refused to use React for years, but if this is normal-ish, it basically cements the decision. An implementation of a ListBox in VGA 0xA0000 framebuffer could be only a little bigger (if even bigger). GtkTreeView, which draws a complete tree/table with columns, resizing, dynamic rows and all the interactions, was 10kloc, afair (now 14). GtkCombobox.c is 5kloc, almost half of that is comments or doxygen.
