Keeping getting this appear in all the input boxes on the page and settings - !:G${Z<¹0

Just randomly, normally on chrome. I login and inside all the input boxes (search and date fields) I get this code entered and i have to got around remove it. This is the code…

!!:G${Z<¹0

That’s so weird, is it filled by Chrome, like an auto-filled password? Is the filled input colored yellow?
