Default settings make the lock icon invisible

Other than this one issue this is a very nice theme, but it's so hard to see this icon...

True, no idea how to fix it, Unity prob hardcoded that one :/. Maybe in new versions (2020) it will work as they are upgrading to UIElements slowly.

Hopefully...

I had hope for a minute that I might be able to make it visible by tweaking the color of the bar behind it.

But Unity chose a color that really doesn't stand out well on any background, I have not had much success.
