Reason for the behaviour is usage of NSTitledWindowMask - even though the title bar is then set to be hidden. The window has to draw semaphore buttons on its own - it is solved as separate subview within the hierarchy. The semaphore buttons are being shown only when the cursor is nearby. Added code to let keyboard shortcuts for close and minimise work properly.

Thanks for this @mst128256 👍

Discussed this with @tonyganch in this morning's meeting and I've updated this pull request to put this behind a new flag so existing apps using frame: false are not affected by this new behavior.

Apps can opt-in to this feature by setting titleBarStyle to customButtonsOnHover on the BrowserWindow options constructor when using frameless windows.

@poiru You mentioned having some edits/differences in your custom implementation of this, we can work those out in any follow up PRs, but this seems solid to initially ship as an opt-in experimental option.

Quick question regarding this, isn't this a private / undocumented API and if so will it prevent apps getting added to he mac app store, this feature might have to be disabled in MAS builds?

I'm not sure, but note that _mouseInGroup is called by macOS, not by us. Not sure if that makes a difference.
