title: welcome page loads when Allow in incognito is checked/unchecked in Chrome
body: <p>I am new to chrome extensions.I used <a href="https://developer.chrome.com/extensions/runtime#event-onInstalled" rel="nofollow">chrome.runtime.onInstalled</a> to load a html page whenever the extension is installed or updated.But when i am testing it in chrome, whenever i check/uncheck Allow in incognito the same html page loads each time.How to avoid this behaviour? I used "incognito":"split" in manifest.</p>
