NIT: IMO it's a bit weird that we'd have an object that's supposed to suppress an interaction also function if no interaction is given.  Should we `ASSERT(interaction);`?  There's no harm in doing it as written, but it does seem a little odd to me :P

Are there any other flags we should also be checking (e.g. `_textInteractionIsHappening`)?

NIT: Is the `<WebKit::SuppressInteractionToken>` necessary?  I think this can be implicit.

Thanks for the review!

Good point! Since the only place that creates one of these is behind `_imageExtractionEnabled`, the interaction should always be nonnull here. I'll add an `ASSERT(interaction);` to clarify this.

I /think/ this should be it, since the intent was just to avoid introducing the interaction just to remove it again when changing focus between editable fields.

IIUC, `_textInteractionIsHappening` is just about pencil, which (I think) shouldn't conflict with the new image extraction interaction.

Yes, it's necessary since this is outside of any `using namespace WebCore;` (since we're in an ObjC @implementation block, this code isn't wrapped inside a `namespace WebKit`).
