What is the usage of the GOOGLE_INPUT_CHEXT_FLAG in Google Chrome Web Inspector?

Question

Now a days I can see that just before the ending of the </body> tag something like below appears:

<div id="GOOGLE_INPUT_CHEXT_FLAG" style="display: none;" input="" input_stat="{}"></div>

I can see this in every webpages whenever I try to Inspect Element in Google Chrome.

Anyone know about this?

Why is this?

What is its usage?

Can it be harmful to my data or computer?

Answer 1

I have got the point. Its because of the extension: Google Input Tools (by Google).

But I am not sure why they use that tagging.
