Texts inside Div stretching when auto-animating

[JarisGV]

I'm trying to user the auto-animate function on a work, but unfortunately when I jump from one section to the next one the texts inside both Divs stretches, upscaling up and down according to the height . I also noticed that this behavior doesn't occur in dealing with code fragments, in this case the texts work properly without streching the fonts vertically.
