User Story

As a developer, I would like to find out why a layout has been invalidated when a reflow is triggered.
Since bug 926371, we can see when reflow are triggered. If a reflow is forced because a JS call (node.clientTop), we can show the JS stack. But if the layout has been invalidated because of some CSS reasons, the resulting reflow doesn't come with any interesting data.

This is a thing BenWa has been working on (part of the profiler trace).
Paul, could anything like this be part of the new Perf Tools timeline view?
Flags: needinfo?(paul)
Yes.

We should show if it's sync or async reflow. If it's a sync reflow, we should show the stack, if it's an async reflow, we should show why the layout has been invalidated.

All reflows with a stack are sync, correct? How can we get the async invalidation reason?
Summary: Show why layout has been invalidated → [marker] Include Async/CSS invalidation reason in Reflow markers
Similar to adding invalidation reason to style markers in bug 1131661
Summary: [marker] Include Async/CSS invalidation reason in Reflow markers → [marker] Reflow: invalidation reason

I believe some of this information was stripped away due to recent stylo changes. I'm closing this for now.
