What steps will reproduce the problem?
(1) Create an HTML file with an element with aria-hidden="true" attribute and some text.
(2) Use CTRL+F to search for the text

What is the expected result?

Text that is hidden to screen readers should not be found using CTRL+F

What happens instead?

The text is found. This can be confusing, e.g., in the presence of material icons. See https://groups.google.com/a/chromium.org/d/msg/chromium-discuss/PbK8dUrq0jE/sffAxwEFDgAJ
