Disable dashicons affects other CSS?

Hi there,

When I select to turn on “Disable Dashicons when user disables admin toolbar when viewing site”

My site’s CSS gets affected. It is really weird – do you know why this is? It’s not just to do with dashicons.

Here is a screenshot showing the styling of the word “upcoming” on an event archive when this setting is turned OFF: https://cloudup.com/cqHFxeENKVi (these events are using Event Espresso 4, paid version)

And this is what it looks like when it is turned ON: https://cloudup.com/cfiLvTZGmD8

It also misaligns my checkbox form label on another page (also Event Espresso 4 related). I didn’t notice other CSS issues, just those two so far. And I did isolate it to that one setting.

I’m curious if this is a bug? If it’s possible to fix, that would be great.

I can send the site to check privately, if you let me know where and how to do that.

Thanks!
