Seems to be an old issue, found several reports of this issue on stackoverflow (some dating back to 2010!):
https://stackoverflow.com/questions/4353836/italic-textview-with-wrap-contents-seems-to-clip-the-text-at-right-edge
https://stackoverflow.com/questions/10243374/textview-cutting-off-a-letter-in-android
https://stackoverflow.com/questions/44074858/android-textview-text-get-cut-off-on-the-sides-with-custom-font
etc.

tl;dr:

This is because the wrap_contents creates a rectangle and the textview text tries to fit in but in italics some part in the starting or end is clipped because it is outside that rectangle made by wrap_content.
