Describe the bug

polybar ignores inheritance lists / multiple inheritance
after updating polybar from 3.4.3 to 3.5.0

polybar inherits from each section in the list

polybar ignores list as if it doesn't exist

Was it working before?
yes

  nope
• If no, what was the last version where this worked correctly?
  for me, 3.4.3

To Reproduce

[inherit_me]
	modules-left   = i3

[bar/main]
	; works
	; inherit = inherit_me 

	; doesn't
	inherit-0 = inherit_me

[module/i3]
	type = internal/i3
