BREAKING CHANGE
Add four new optional properties to menus in Electron. The four properties are:
'before'
'after'
'beforeGroupContaining'
'afterGroupContaining'
'before/after' - provides a means for a single context menu item to declare its placement relative to another context menu item. These also imply that menu item in question should be placed in the same “group” as the item.
'beforeGroupContaining/afterGroupContaining - provides a means for a single menu item to declare the placement of its containing group, relative to the containing group of the specified item.
* Propagate referrer to new windows
Fixes#9205
* Rearrange -new-window event arguments for backwards-compatibility
* Plumb referrer policy through guest-window-manager
* Document the Referrer structure and its uses
* Add tests for referrer in new windows
* Docs nits
Fixes#12311
Right now it throws a new error when the file is even require()d, but this isn't ideal as there are cases where everything is mass-required, such as Spectron. Instead, we should throw an error on non-Darwin environments only when the IAP methods are invoked.
* Fix child touch bar items not updating
Deep children of a TouchBar didn't cause the top level touch bar to update, now they do
Fixes#11761.
* Remove unused newValue property in TB setter
* add function to remove leading/trailing separators
* change const name for clarity
* add spec to check filtered separators
* clean method and add edge case spec per review
The event is emitted when the OS is rebooting/shutting down, and allows
an electron app to call `e.preventDefault()` in order to delay shutdown
and exit cleanly.
