ERROR when putting "else { }" block below "#else"

Code to reproduce this issue:

#include <stdio.h>
int main()
{
	int i;

	scanf("%d", &i);
	if (i > 10) {
		printf("big\n");
	}
#ifdef ONE_MORE_CHANCE
	else {
		printf("small\n");
	}
#endif

	return 0;
}

What tree-sitter parse gives:

Just ran into this with some code that looks like:

	if (argc > 1 && strcmp(argv[1], "--check") == 0)
		BootstrapModeMain(argc, argv, true);
	else if (argc > 1 && strcmp(argv[1], "--boot") == 0)
		BootstrapModeMain(argc, argv, false);
#ifdef EXEC_BACKEND
	else if (argc > 1 && strncmp(argv[1], "--fork", 6) == 0)
		SubPostmasterMain(argc, argv);
#endif
	else if (argc > 1 && strcmp(argv[1], "--describe-config") == 0)
		GucInfoMain();
	else if (argc > 1 && strcmp(argv[1], "--single") == 0)
		PostgresSingleUserMain(argc, argv,
							   strdup(get_user_name_or_exit(progname)));
	else if (argc > 1 && strcmp(argv[1], "--wal-redo") == 0)
		CallExtMain("neon_walredo", "WalRedoMain", argc, argv, false);
	else if (argc > 1 && strcmp(argv[1], "--sync-safekeepers") == 0)
		CallExtMain("neon", "WalProposerSync", argc, argv, true);
	else
		PostmasterMain(argc, argv);
