Heirline should refresh winbars on `on_colorscheme` as well

Hey, I just noticed that changing colorscheme (or background) as described in cookbook nicely reloads them for statusline but doesn't for winbars.

It's clear that change gets broadcasted to statusline here

heirline.nvim/lua/heirline/utils.lua

Lines 399 to 401 in 9a48413

    
           require("heirline").statusline:broadcast(function(self) 
        
               self._win_cache = nil 
        
           end)

but the same does not happen for winbars and most likely tabline too (but I am barely using colours there to notice) .

Is that something that users could add themselves or would it require change in heirline?

Thanks!

you're right, that needs to be updated. Anyway, I didn't really ever noticed that, and I tested colorscheme changes pretty wildly when developing kanagawa.. Resetting the window cache for components is only meaningful for components that get updated on certain autocmd events, which means that, eventually, they'll be refreshed anyway.

Works perfectly, thank you for rapid fix!

	require("heirline").statusline:broadcast(function(self)
	self._win_cache = nil
	end)
