undesired alt tooltip shows up, is this a virus or a bug ?

[BrainPill]

Hi my server setup is WAMP offline.

My virus scanner is Windows Defender.

 

I have created a form in html where the user can submit a series of links. I do not use the attribute alt or other javascript code for a tooltip on the page.

 

I created a random https address url list to check the header status and when 200/301/302/303 true; I use file_get_contents() to scan the (malicious) sites their content.

 

now 1 of the input fields has a https link address and when hovering over the input box there will be a tool tip with the link address.

The other input form fields dont give a tooltip ( alt popup) when hovering over it.

 

Is this a virus or can it also be a bug? I read online about a tooltip virus.

Are you sure this isn't just your browser's auto-fill? Like this 'tooltip' only includes what you've previously written into similar fields?

it could be.

I tested it now in another browser (Brave) and here the web address didnt give a tooltip.

 

But what causes these differences? Autofill?

How can I control that?
