Invisible arrow icon in dark mode in MultiMC

Description of bug

There is an arrow icon that should show up when the width of the window is too small to fit all the buttons in the top bar. But it is invisible. It is visible only when the cursor is hovered over it. I'm attaching screenshots below.

In the red square there is supposed to be an arrow. The arrow is only visible by hovering over it

This is on Arch Linux MultiMC Version 0.7.0-4233 downloaded from the AUR multimc-pkgbuild.

Steps to reproduce

1. Resize the window, making the width small.
2. When a button gets hidden, there should be an arrow to see the whole top bar.
