What happened?

The icon of the forward button is ever so slightly offcenter, probably only a pixel or 2 off, but it is noticeable when hovering over the button or better seen by hovering over it in Browser Toolbox. Interestingly, the back button icon appears to be correctly centered

Reproducible?

• I have checked that this issue cannot be reproduced on Mozilla Firefox.
