[menu-bar] keep sub-menu open when moving diagonally over other menu items with the mouse pointer

[jouni]

Describe your motivation

Navigating sub-menus with the mouse is tricky if you need to move the cursor to the sub-menu without hovering over other menu items in the parent menu. You basically need to move the cursor through the narrow parent menu item to reach the sub-menu. This can be really difficult for people with motor control issues / movement disabilities.

Describe the solution you'd like

The common solution to this issue is to provide a "safe zone" that covers the area from the mouse pointer to the edges of the sub-menu which can partially overlap the parent menu items, allowing the user to move the mouse cursor over this safe zone without closing the targeted sub-menu.

Here’s an example:

Describe alternatives you've considered

The naive solution is to have a delay (e.g. 1 second) in closing the sub-menu even when other parent menu items are hovered. This might solves the original issue, but creates another one that it becomes more tedious to navigate multiple sub-menus in quick succession because you need to wait for the previous one to close before opening the next one.
