EventTargetData: Avoid inlining a GarbageCollected object Use a combination of a mixin, private inheritance, and a separate object to allocate to avoid the GC_PLUGIN_IGNORE. In addition, having a proper mixin interface actually allows for the EventTargetData reference to actually escape onto the stack or heap, which would otherwise be hard to check and enforce. The only trade off is that this approach minmally regressed tracing performance of EventTargetDataMap because the GC has to lookup the header of a mixin object.

Chromium is an open-source browser project that aims to build a safer, faster, and more stable way for all users to experience the web.
The project's web site is https://www.chromium.org.
To check out the source code locally, don't use git clone
! Instead, follow the instructions on how to get the code.
Documentation in the source is rooted in docs/README.md.
Learn how to Get Around the Chromium Source Code Directory Structure .
For historical reasons, there are some small top level directories. Now the guidance is that new top level directories are for product (e.g. Chrome, Android WebView, Ash). Even if these products have multiple executables, the code should be in subdirectories of the product.
