Input cursor caret bug on IOS

Hello guys, i have a problem when the position of an input changes after an animation, the caret cursor is not in the correct position as the image shows:

Iit is as if it stays stuck and after doing another action within the app corrects its position and is placed in the right place, its a really weird behavior, i tried to hide it with CSS but it does not work, it stays stuck in its initial position and the CSS classes seem not to affect it. I don’t know what else to do, please help me. This only happen on IOS.
