The general approach (deferring the selection change when performing a synthetic click) seems reasonable. Should we also invoke the selection change completion handler in the case where we don't end up completing the synthetic click?

Nit - reviewed by line should move up before the description.

> +    WTF::Function<void()> _selectionChangedBlock;

This should probably be something like `m_selectionChangedHandler` or `m_selectionChangedFunction`, since it's not an Objective-C block (and it's also a member of a C++ class).

Nit - extra newline here.

Nit - space after the =

Ditto.

We should assert that `m_selectionChangedHandler` is not set here, and/or invoke the previous handler if it is set.

> +    m_selectionChangedHandler = [point, granularity, isInteractingWithFocusedElement, completionHandler = WTFMove(completionHandler), webPage = makeWeakPtr(*this), this]()mutable {

Nit - space before the `mutable`.
