[A11y] Non-conflicting initial empty document root id

This matches the code in Mac, Linux and Android where the crash does
not occur. The intention was to with this change on all platforms
when stable ids landed in CL:5328829, but somehow, these lines were
lost on Windows and Fuchsia. With this change, Windows and Fuchsia
now match the code in the other platforms, and uses a special
non-conflicting id for the root, rather than 1, which can conflict
with a node id in the initial real document.

Logo Chromium

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.

If you found a bug, please file it at https://crbug.com/new.
