I was trying to tame 2 Komodo Dragons, i gave them roughly 8 stacks each and neither would tame, i thought it was weird so i made a creative world and tried it no matter how many times i tried it wouldn't work i used a whole inventory and still they wouldn't tame.
if anyone knows any news on this possible fix or if they are working on it please let me know because i had some fun plans involving them thank you.

I too am having the same issue 😞 been dropping stacks in creative for a min

Made a pull request for this, that fixes it
