NSEventModifierFlagFunction specified to -setKeyEquivalentModifierMask warning is repeatedly logged to the Editor log when interacting with the Editor menus on macOS

How to reproduce:
1. Create a new Unity project (URP Blank template)
2. Open the Editor and interact with the main menus or trigger any assembly reload
3. Open the Editor.log and observe the results

Expected results: No "NSEventModifierFlagFunction" warnings are logged
Actual results: "NSEventModifierFlagFunction specified to-setKeyEquivalentModifierMask: for item <NSMenuItem: 0x... SDF, ke='Command-F12'>, but is only supported for system-provided menu items; will not be used" is logged repeatedly (24 times in a ~4 hour session)

Reproducible with: 6000.0.76f1, 6000.3.16f1, 6000.4.8f1, 6000.5.0b9, 6000.6.0a6

Reproducible on: macOS Tahoe 26.4.1 (M1)
Not reproducible on: No other environment tested

Notes:

• All warnings reference the same key equivalent (Command-F12) and the "SDF" menu item identifier
• The warnings are emitted by macOS AppKit (NSLog), not by Unity's logging system, so they do not appear in the Editor Console — only in the Editor.log file via stderr
• Per Apple's documentation, the NSEventModifierFlagFunction modifier is only valid for system-provided menu items. Unity is assigning it to its own menu item, which macOS silently ignores ("will not be used")
• Spike of warnings occurs after assembly reloads (menu rebuild) and on subsequent menu interactions
