[A11y] Adjust fix for "De-flake AccessibilityContenteditableDocsLi"

crrev.com/c/5180532 fixed a flake that was caused by previousOnLineId
being unexpectedly null. The fix was to find the highest LayoutInline
ancestor of a newly-attached text node and mark that inline object
dirty so that previousOnlineId values would be recalculated.

This fix introduced a performance regression in two tests where many
text nodes were during the test. Given that the flake being fixed seems
to be limited to a whitepsace-only node, attempt to improve performance
while preserving the fix by only marking the subtree dirty when a
whitespace-only node is attached.

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.
