[mac-a11y]: avoid performance issues with text range attribute retrieveal

Recent versions (and possibly older) of Mac OS and VoiceOver request
NSAccessibilityAttributedStringForTextMarkerRangeParameterizedAttribute

on nodes which contain large amounts of text e.g. divs wrapping almost
the entire page's contents.

As a result, VoiceOver repeatedly blocks with not responding messages.

Work around this issue by limiting the text retrieved to 200 characters.

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.
