Client changes rune page to preset Inspiration page last second after rune page saves [CLIENT]

Second game in a row where I finish doing my runes with 2 seconds left. The page clearly saves, and I close it to make sure it saves (since if it doesn't it asks you if you want to save and doesn't save it anyways). It changes to Inspiration preset page anyways. Obviously reproducing this bug would playing the game suboptimally, but it seems to correlate with saving the page a couple seconds before the game starts.
