Autocomplete Issues (CTRL+TAB)

While using firefox I have the habit of using CTRL+TAB to cycle through tabs, but recently this problem started to haunt me: If I CTRL+TAB out of a Twitch Chat it still acts as if I simply pressed TAB, even if I have not entered a single letter, cycling through namesat the same time I leave the tab. Could this be corrected so it ONLY cycles if you use TAB or SHIFT+TAB?

You should post this instead to our bug tracker on Github:
