[FIXED] Why input elements "value" attributes are sometimes not presented in the HTML?

Issue

Sometimes input elements are visually presenting their values however these values are not presented in the element HTML. Not as "text" and not as "value" attributes. Like here
Actually, it's a value attribute, but it is hidden.
I mean even existence of value attribute itself is hidden.
I'd like to understand why those value attributes are hidden ?

Solution

In case of text type input elements (and some others as well), in native HTML value attribute of the element presents its default value.
The text value inserted by the user is not presented there, so only the default value will always presented in value attribute.
In case no default value is set for that element, the value attribute will not be presented in the element HTML.
Similarly to the presented in the attached screenshot.
