Specification
https://xhr.spec.whatwg.org/#interface-progressevent


Summary
ProgressEvent is available in service workers, allowing developers to construct 
progress events with lengthComputable, loaded, and total attributes. This 
aligns service workers with other worker contexts and the XMLHttpRequest 
Standard.


Blink component
Blink


Web Feature ID
xhr


Motivation
Blink exposes ProgressEvent in Window, DedicatedWorker, and SharedWorker 
contexts, but not in service workers. Exposing it in service workers closes 
this gap with the XMLHttpRequest Standard and allows code that constructs 
progress events to be reused across worker contexts. The change reuses the 
existing implementation without exposing XMLHttpRequest or adding automatic 
fetch progress events. Draft implementation:
