@aleventhal, do you happen to know whether enabling content capture influences the speed of accessibility code? According to the pinpoint results (ContentCaptureTriggeringForExperiment feature flag (which is enabled in the field trial testing config) seems to get rid of the regression, but it's not clear why.

Hi Oksana, I never heard of ContentCapture before. Does it interact with the accessibility tree, layout or DOM? Are there some docs you can point me to? Feel free to ping me on chat/email

Started an email thread with some more details.
