Add the is:inline directive explicitly to silence this hint.

i have been using this theme for over a year and i have the same issue now. i've tried everything i can think of to fix the errors but i'm stuck after upgrading my project. i have tried clean installs too, but i'm still running into incompatibility errors like you.
