section not themed on helium

After the new update (zen mode) on Helium, window controls arent themes properly (?) becaue they arent the same color as the rest of the bar

Should be fixed by Helium or edit things in the theme colors ?

Start by reproducing the issue in Helium's zen mode and inspect how the window controls are themed relative to the rest of the bar. Determine whether the mismatch belongs to Helium or the theme colors; done means the controls match the surrounding bar color.
