Separators width & height not affected by theme

[imabuddha]

I've read the wiki, and I've set separators_height and separators_width in my theme. However these values have no affect on lain.util.separators.arrow_right.

Looking briefly at the source it also seems that the values are hard-coded & no reference is made to beautiful.

output of awesome -v and lua -v

~ ❯ awesome -v
awesome v4.3 (Too long)

expected behavior

Setting values of separators_height and/or separators_width in theme should affect separators.

actual behavior

The values of beautiful.separators_height and beautiful.separators_width (as set in the currently loaded theme) have no affect on separators.

steps to reproduce the problem

1. Set values of separators_height and separators_width theme
2. Add arrow(s) to a wibox
3. Reload awesome
