Turns out that if you copy text from OneNote and paste it into something that can accept either text or images, it decides you must want a bitmap rendering of your text. I pasted the text into this posting box and got the image, then pasted it again into the image's alt text and got text. Incredible. 0/10 ux, principle of least astonishment maximally violated
