Textarea resize bug on iOS

Hi everyone, couldn’t find a solution here on the forum or in the web. Only on iOS (both simulator and real device), when I focus on a textarea an it resizes to fit the keyboard addition, actually the “clickable” surface keeps the original size. I installed ionic keyboard plugin, that resolved the header bar diappearing but not this problem.
Here is a video showing the problem. On actual device, with a virtual keyboard the proble is the same.
Thanks everyone for the help, ask for more info if I forgot something
