@alex there is some weird behavior on iOS when posting or replying: if words are chosen from autocomplete suggestions, they are not completed in the input most of the times. Also when using dot, comma or colon the last character from the previous word is removed most of the time.

My guess is this is related to replacing emojis and user handles, there might be some index that's wonky in some cases.

(First I thought it was some Apple bug, but Soapbox sites seem to be the only affected ones)
