[Sebastian Hengst [:aryx] (needinfo me if it's about an intermittent or backout)]

Alexandre, can you take a look at the bug? It's a frequent failure.

Comment 6

[Alexandre Poirot [:ochameau]]

Attachment: Bug 1667282 - [devtools] Fix browser_resources_network_events.js intermittent.

We should only assert updates attribute on resource-updated,
as we aren't guaranteed how many updates we will have in resource-available.
That's because of resource throttling. Updates may be coalesced into available,
but we can't predict how many.
