Weird text colors showing up?

I’m finding myself occasionally running into shades of text I can’t read properly without highlighting them ( black text on dark theme, white text on default theme ). As far as I can tell this isn’t intentional text shading either, as it shows up in posts I’ve made or my friends have made where I know they aren’t coloring their fonts on purpose.

not directly related, but similar: While editing the title bar on the dark theme, I can’t actually read the title until I deselect it, not a major issue, but modestly annoying.
