@ruslantimofeev After some investigation, this is occurring because of the way Chrome mimics user input in its autofill feature (this issue does not happen on Firefox). Moreover, there is no way to detect if chrome autofill has been used to fill in data via javascript. We're going to close this issue since we cannot control how Chrome fills in the data via autofill.

Let us know if you have any other questions.
