Right click context menu flickering

[luiz734]

Describe the bug The popup that opens when I right-click some links keeps scrolling up and down to quickly, making it impossible to click some options.

To Reproduce

1. Right-click on links in any page.
2. Move the cursor up and down.

Expected behavior The context menu should not flick.

Setup information

• OS: Arch 6.6.10-1-lts
• Installation method: AUR
• Firefox version: 121.0.1
• Theme version: 112.r0.g9b88fd9-1
• Optional features enabled: None

Additional context

• I noticed that the issue only happens when there is no space to show the full popup, requiring a vertical scroll.
• I've checked that this only happens while using the theme.
• Despite disabling extensions that could be the cause, such as Greasemonkey, the issue persists.

Duplicated of #728. A v121.1 release of the theme was made fixing that regression.
