How do you change the tooltip text of an HTML title element?

Question

If I mouse over the tab of a page in a web browser, a tooltip appears showing that page's full title. I would like to change that tooltip; e.g.

<title title="Some other text">Name of the page</title>

Is this even possible?

Answer 1

There is no solution to update title as tooltip of title tag in head

Answer 2

No, not possible.

You can't change the tooltip of the page tab to be different than the content of the <title> element.
