Reply Keyboard can have not more than 10 buttons

When I'm trying to add 11-th button to the Reply Keyboard, it stops sending messages.

In master/src/AsyncTelegram.cpp: void AsyncTelegram::sendMessage
It turned out that 512 is not enough:

if (keyboard.length() != 0) {
    DynamicJsonDocument doc(512);
    deserializeJson(doc, keyboard);
    JsonObject myKeyb = doc.as<JsonObject>();
    root["reply_markup"] = myKeyb;
}

If I change DynamicJsonDocument doc(512); to DynamicJsonDocument doc(1024); it works fine.
Maybe it should be changed to BUFFER_BIG, or 1024 is enough.
Have a good day.
