Document AI, upside-down text not recognized, when on a page with majority right-side-up text

[iantolan]

When I call the DocumentAI API with an image or pdf with a mix of right-side-up and upside down text. 

The upside down text is not picked up. Interestingly, if I crop the image so that the majority of the text is upside-down, the upside-down text is picked up, but the right-side-up text is then missing from the response. 

In both cases, the sideways text is picked up without issues. 

Any tips on why this might be the case, or ways to detect both upside-down and rightside-up text in the same image?
