Let's suppose I clicked this item, then scrolled around in my script, and I then wanted to check out the warning's line again. It wouldn't work without selecting another item first.

Should be an easy fix by setting `allow_reselect = true` in the underlying tree.

### Steps to reproduce

Array msg;
	msg.push_back(p_path);
	msg.push_back(p_line);
	msg.push_back(p_enabled);
	_put_msg("breakpoint", msg);
	TreeItem *path_item = breakpoints_tree->search_item_text(p_path);
	if (path_item == nullptr) {
		if (!p_enabled) {
			return;
		}
		path_item = breakpoints_tree->create_item();
