1772347 - Content process targets destruction isn't notified to the client

Status: RESOLVED FIXED

(DevTools :: Framework, defect, P3)

Description

[Alexandre Poirot [:ochameau]]

This only happens when we destroy the target, but the content process itself isn't destroyed.

When the process is destroyed, the following code will kicks in and notify about the target destruction:

In bug 1772310, we will start destroying content process target actors, while the process keeps running and start having some side effects because of this.

Attachment: Bug 1772347 - [devtools] Ensure that content process targets destruction is notified to the client.

That, when the target is destroyed for any reason other than the process destruction.
For example, when we stop observing for content process targets.
