Images uploaded inside Post Text body are instead uploaded as main/featured post attachments when creating new thread
Steps to re-create:
I start a new thread
I upload an image
I tap the Post Text body
I upload an image to be inserted into the body (Post Text)
Nothing appears to happen after upload completes; no image embed markdown is inserted
I tap back and see the image I just uploaded to be inserted into the body has instead been uploaded as the main image to be featured in the thread, supplanting the image initially uploaded
