api.Document.startViewTransition.updateCallback_parameter - Incorrect Firefox support #29455

Description

@mathewhodson

What type of issue is this?

Incorrect support data (example: BrowserX says "86" but support was added in "40")

What information was incorrect, unhelpful, or incomplete?

The updateCallback parameter of the startViewTransition() method shows only preview support in Firefox and mentions that you need to explicitly set the dom.viewTransitions.enabled preference.

What browsers does this problem apply to, if applicable?

Firefox

What did you expect to see?

I believe updateCallback parameter always had the same support as the main feature in Firefox, so this should show support since Firefox 144 same as the main startViewTransition feature. The pref was enabled by default on all channels in bug 1985809, so it should be removed from the compat data.

Did you test this? If so, how?

Ran this in the web console: document.startViewTransition(() => console.log("updateCallback supported"))
