Perf test for balanced multicol with tall list item markers.

If inside a balanced multicol container, we have a performance problem
if list item markers are just a little bit taller than the line that
they are next to. The problem is that this provides a very small
NGLayoutResult::MinimalSpaceShortage(), so that we'll end up performing
very many layout passes, stretching the columns just a tiny bit at a
time. The test has no perfect break opportunities, so the end result is
that everything fits in one column.

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.
