Wrong colors of a button, if used in a blog post

[aleksandia]

I noticed that if I place a button in a blog post the colors of the button will be inocrrect, for example if I hover over a button the color of the text is dark instead of being white. If the button is used on a normal page the button works just fine.
I don't know if this is a configuration issue on my end, but it does seem odd.
I tried a couple of fresh wordpress installations and had the same problem every single time.

Just thought I'd share that.
