Regression: initial character block doesn't show up in Korean during review

[iopq]

Korean IDEs usually start the character as a composition where you type each alphabetic symbol one at a time until the character block is completed

I just noticed the very first one doesn't show up, but if you complete it or delete it it works. This is consistent for every review, so every single card is affected. If the card is only one block it won't show up as correct even if I already typed it in, I have to press space for it to show up and register
