Error with random position mode

[julien-deramond]

Whatever the data set as input in the extension, when "Random position" is checked:

www.youtube.com/:1 Error handling response: TypeError: Cannot set properties of null (setting 'src')
    at chrome-extension://eficfcfnfcemmmnmniolgbiggengpckp/content.js:81:23

IMO it is linked to #45 and the selectors which have changed in YT.

I don't know enough the extension but the following change could help for a fix:

-    // Target only ytd-rich-item-renderer element and not ytd-rich-item-renderer with id content for the main page
-    let cards = activeScreen.querySelectorAll('.ytd-rich-grid-media:not(#content):not(ytd-display-ad-renderer)')
+    let cards = activeScreen.querySelectorAll('.ytd-rich-grid-media#dismissible')
