It seems like this should either copy the contents or take a reference to pendingEditorCommands. If we don't mind stomping the contents of pendingEditorCommands a reference more straight-forward. If we do mind, we cannot use std::move, right?

We don't mind stomping the contents of that Vector, even if we don't stomp them in the end. But in WebEditorClient::handleKeyboardEvent() the Vector isn't used after the WebEditorClient::executePendingEditorCommands() call (whichever of the two is performed), so moving the object along into that invocation isn't harmful.

Passing in the Vector by reference would make sense if we'd use that Vector later in handleKeyboardEvent(), but we don't. There's nothing wrong with passing the object by reference, but it's not necessary. Hence the proposal to use std::move() and pass it by value.

It's slightly more efficient because you don't have to construct a new object and matches what we usually do in that situation.

I see, WebEditorClient::executePendingEditorCommands() only reads from the Vector but doesn't store it, so taking the const reference of the Vector is indeed more intuitive.

Please update also the header to fix the build.

You need to update the header too.
