Ordered list styles not working

Ordered list styles not working. (Showing 2 styles at the same time: number and e.g. letter)

This is a sample site with all plugins disabled. When I switch to default theme, lists are working again.

Code that I’m testing:

<ol style="list-style-type: lower-alpha;">
	<li>ee</li>
	<li>fd</li>
	<li>fd</li>
	<li>df</li>
</ol>

Site spec:

# SITE_URL:                 https://marfx.pl/4ga
# HOME_URL:                 https://marfx.pl/4ga

Show On Front:            page
Page On Front:            main (#53)
Page For Posts:            (#0)

I’m not sure what exactly can be causing such behavior.

I’ve tested on my other site. It was archived and not updated anymore and it worked on Customizr 4.1.28
