Transparent line in chromium

[d8a-base]

If you're reporting an UI issue, make sure you take a screenshot that shows the actual bug.

Chromium (Version 102.0.5005.61) displays a transparent line between searchbar and the website.

I'm using Openbox with picom as compositor but this bug was easily reproducible in a virtual machine with XFCE and their compositor.

Dracula was installed via AUR package: https://aur.archlinux.org/packages/dracula-gtk-theme

This transparent line in not present in other GTK themes I tried.

[rc2dev]

Same issue on Brave (Version 1.40.107 Chromium: 103.0.5060.53).

I installed Dracula by cloning the repo, and I'm tracking master.
