I've noticed that in the Choco Dark and Windows 10 Dark themes some of the editor window toolbar icons are virtually unreadable.  They are still there but they are written in black or a very faint unreadable blue.  I was wondering if this is a bug or a problem on my end.  I've looked at the "Customize" window for these icons but it does not seem to have an option for changing the colors, just the icons themselves.  The problem icons I've noticed so far are:

Undo
Redo
Strikethrough
Subscript
Superscript
Crop Image
Uppercase
Lowercase
Invert Image
Capitalise
