1145627 - [ServiceWorkers] matchAll doesnt work the first time is run just after sw installation

Status: RESOLVED INVALID

(Core :: DOM: Core & HTML, defect)

When installing a SW and then asking for matchAll, the first time that sw has been installed, we get an empty array.

Reload the page and ask for a matchAll and you'll get the array of clients that the sw is handling.

Adding sw.html and sw.js to try this out.

Was doing the same test in canary and also I'm not able to get the clients the first time the SW is registered.

Again, if I refresh the page I can get the message from the worker. Is that the expected behavior?

Right.  The page is not controlled on the first load.  I believe we need the .claim() API for the SW to control the first page immediately in the oninstall event.

Closing since this is the intended behavior.
