Is this used anywhere?

Good point. I thought I needed it when I was first fixing the bug. Will remove.

Does this need to be in the header file? Normally, we don’t have to declare methods if we’re just overriding something in NSView. We only need to put the method in the header if it’s a new method that some other class is going to call.

Is there a good reason to call maintainsInactiveSelection here? It’s just a function that always returns NO.

Do we expect people to make subclasses of WKView and override the maintainsActiveSelection method?

For BOOL it’s YES and NO. The values false and true are of type bool.

r- for now because I think Jon is going to change this to normal WKPage API rather than WKView API (which really should not exist at this point).

In these C API headers, we usually name all parameters, including booleans. Please call this one “maintainsInactiveSelection” or something.

> +    void setMaintainsInactiveSelection(bool newValue);

No need for the name here, though!
