Add Long Animation Frame Timing

[Elchi3]

Another example PR for bundles that could be exported to web-features when we run the OWD BCD collector for new browser versions and new features shipping with them: mdn/browser-compat-data#22280

I'm pretty sure a bundle for "Long Animation Frame Timing" makes sense.

For "Navigation Activation", I don't know if this part of something larger. It has its own entry on Chromestatus at least.

Searching for "NavigationActivation" in the spec, the PageSwapEvent interface is also related, by having an activation member. But that's not in mdn/browser-compat-data#22280, was it not shipped together?

[noamr]

No, it hasn't shipped yet. PageSwapEvent builds on top of the NavigationActivation feature.

I see, thanks for confirming!

@natechapin @noamr as owners of https://chromestatus.com/feature/5076557983121408, can you weigh in on whether "navigation activation" should be consider a feature in its own right, or if it's a part of the Navigation API or some other feature?

100% part of the navigation API.
It uses navigation-API existing interfaces like NavgationHistoryEntry and you access it via navigation.activation

How about PageSwapEvent? That touches both navigation API and view transitions, but should it be said to be mainly part of one of those features? It's not a problem if it's correctly described as being part of two features at once, but it's not a situation we've had so far in web-features.

I'd say that it's in the neighborhood of PageTransitionEvent (pageshow/pagehide) and PageRevealEvent, and it links to the other features.

When we give an overview of view transitions we should link back there.

I think the conclusion here is that Navigation Activation should be part of the Navigation API, at least in the long run. @Elchi3 can you drop that feature from this PR, and change the tag in BCD if one was already added?

Curious, LOAF isn't an abbreviation acronym of Long Animation Frame.

[noamr]

It's LoAF
Also Radar is not an exact acronym of (RAdio Detection And Ranging)
