説明

When autocomplete is enable via about:settings, we display a NSPopover (https://github.com/LadybirdBrowser/ladybird/blob/master/UI/AppKit/Interface/Autocomplete.mm) to show autocomplete results. On some macs, this popover removes focus from the location text field when results change.

前提条件: macOS AppKitObjective CNSPopoverFocus management
初心者向け度: 30
調査方針: Investigate the NSPopover implementation in UI/AppKit/Interface/Autocomplete.mm, specifically how the popover responds to changes in its content and whether it inadvertently becomes first responder. Review the linked PR #4156 for context on previous changes. Check the video attachment to reproduce the focus stealing behavior, then adjust the popover's window level or first responder status to prevent stealing focus from the location text field.
