MS Edge extension listening to key press in an SSRS Report

I tried to listen to a keypress via Edge extension on an SSRS Report but as soon as I click into an input I do not get any console logs anymore, while seems to work on other pages. How to fix it? Manifest

{
    "name": "Test",
    "version": "1.0.0",
    "description": "test",
    "manifest_version": 2,

    "background": {
        "scripts": ["js/background.js"],
        "persistent": true
    },
    "content_scripts": [{
        "matches": ["http://*/*", "https://*/*"],
        "js": ["js/background.js"],
        "run_at": "document_end"
    }]
}

Background.js

document.addEventListener("keypress", function(event) {
    console.log(event)
    if(event.keyCode == 117)
    {
        document.querySelector("input[type='submit']").click()
    } 
});
