There is a route to call TabParent::SetDocShellIsActive() from js. The call stack was like the following.

By the crash report, TabParent::SetDocShellIsActive(/* isActive */ true) seemed to be called before WebRenderLayerManager::Initialize() call.

Correction:

By the crash report, TabParent::SetDocShellIsActive(/* isActive */ false)
> seemed to be called before WebRenderLayerManager::Initialize() call.

From the crash report, Bug 1399850 seems similar, but it has the following error like Bug 1399850 comment 8.

The crash did not happen since Bug 1401849 fix.
