Anchor icon is invisible

bug

#1

In 1184, I’ve noticed that sometimes the button to pick the anchor to use for a component appears invisible.
At first I thought that it had completely disappeared, but I realized that it just wasn’t displaying. If I click on the area where it supposed to be the dialog appears as normal, as you can see here:

It seems to be kinda random. I’ve seen it pop back into existence sometimes when I change glyph view.
