### Description
Fixes a potential recursion where CETV tries to set it's frame to a negative number (due to overscroll & scroll inset weirdness). This adds a super simple sanity check to make sure we limit the textview to a `0` frame at minimum.
This hang would occur when no content is present, making the content size an odd number, which also makes scroll views freak out on macOS.
