Bug Report

Description

The title bar hamburger menu (☰) overlaps with the hover-triggered dropdown menu that appears when hovering over the second button in the sidebar, causing both menus to visually collide.

Actual Behavior

The title bar hamburger menu renders on top of the sidebar's hover-triggered menu, making both menus difficult to use and visually broken.

Additional Context

The hover menu is triggered by the second button in the sidebar (not a click). The overlap suggests a z-index or event handling conflict between the two menu components.

What Should Happen?

Expected Behavior

The hamburger menu and sidebar hover menu should not overlap. Z-index or positioning should be managed so both menus render in their own space without collision.
